I have a 2004 30 foot Winnebago Brave. I just had the original TV antenna replaced with a King Jack antenna and got rid of the crack handle. Also replaced the front and bedroom TVs with smart TVs.  Since being replaced, I get no cable TV on either main or bedroom TVs and the bedroom TV does not find any of the antenna stations. I have a Winngard switch box and have verified with a Winngard technician that it is functioning properly. I don't believe in coincidences and was wondering if there is a common connection at the original antenna location that could have inadvertently been cut or disconnected? No coax was replaced when the antenna was replaced.  Thanks for any help/suggestions.
 
I might not be calling it the right thing. But basically its a component that was made by Winngard that allows your to select either Cable, Antenna or VCR to 2 different TVs. Internally, it just mechanical switches except for the 12vDC used to amplify the antenna. I contacted Winngard and was pleasantly surprised that they responded within 20 minutes.  Since TV 1 worked correctly when connected to TV1 antenna on the box, I connected the TV to TV2 on the box and the TV worked fine.
 
You stated that you're not receiving CABLE. Are you receiving OVER THE AIR channels? On the smart TVs when you do a channel search you have to select whether you are searching for cable or over the air channels.
 
I am receiving over the air channels on TV 1, not on TV 2.  Neither TV is picking up cable.
All was working fine until the antenna was replaced. Since replacement, TV 1 picks up over the air. TV 2, and outside TV do not. None pick up cable, even after redoing channel search. 
 
Obviously things are not hooked up right. All you can do is check where each and every cable is connected to your antenna, switch box and the TVs themselves.

You made a lot of changes all at once. Somewhere there is a cable (or cables) not connected to the correct port.
 
IF you get NO cable TV then the middle cable on the wall plate (The wall plate with the switch and the light and the 12 volt outlet and antenna connection) is not proper. Likely since you do not get OTA on TV-2 I'd guess you've swapped the middle and (Looking at it from the rear) the RIGHT cable. (TV-2)

Sorry to hear of your downgrade of the antanna. That antenna is no where near as good as the one it replaced.

Since the original crank up OTA antenna on my Adventurer just fell apart while on vacation, I was thinking about getting one of the new King permanent mount antennas so we wouldn't have to fool with the crank anymore. Please tell me why you have such a low opinion of them. The one I am replacing is 2005 technology that can't get HD, so I can't see how a new King will be any worse. If you have facts and experience with them, please share.
 
John Stephens here is my write up on my Jack antenna, installed in 2013 and it works great.  Should be enough info to use for a search.  Dick nvrver

Yes, obviously something was not hooked up right, but I'm stumped. Supposedly, the only coax the installer had to fuss with was disconnected from the old antenna and connecting to the new. The line runs to a plate to provide the 12Vdc for the antenna. It has three connectors. 1. is labeled antenna is connected to the antenna, 2. is labeled to the Winngard 'antenna in' and 3. is not connected tp anything.  Swapping 1 and 2 did not resolve the issue.  Since all the cables in the coach appears to be routed correctly, I am suspecting that there must be an issue at the connector at the antenna. Not sure if the is a splitter joining the coach cable input.  I'll wait until the installer comes back next week and have him fix it.
As for changing out the original antenna, the crank handle was is bad shape and it was a pain turning the antenna to find the best signal.  I like the LED slights helping to adjust the antenna and reception seem slightl improved.
 
Why do I have such a low opinion.. Ok.
Basically they don't perform up to advertisement. Oh they perform to Specs all right but  I know how to read the spec sheets and they are NOT better than the Batwing

A basic Batwing (Sensar III) without enhancement is, at the worst, twice the antenna the JACK is (And that is the directional model) it is way way way better than any Omin-directional made.

Add the wingman and you double it again making it twice as good as it was on UHF.

That's nearly twice the range.. ON UHF. 1.414 on VHF.

BUT the range is increased by decreasing the beam width 

How to imagine it

You need two pair of binoculars.  1 low power 'Opera glasses" and the other high power "Field Glasses"

Look at somethign distant.. You can see it better with the higher power "Field Glasses"

But. you will see MORE (a wider field) with the Opera.

So if you are parked in the middle of a lot of stations. Yes the Jack is better

But darn few RV parks are so located.

The ANTENNA has absolutely NOTHING to do with whether or not you can get HD. ANYTHING that can serve as an antenna will pick up the signal...ANY signal. I have watched HD broadcasts using a 3-foot piece of wire stuck in the antenna connection on the TV. Worked fine.

This nonsense about needing a "digital" or "HD" antenna is nothing more than sales BS. It sells a lot of unneeded TV antennas, though.

John, thank you for your lengthy answer to my question. Unfortunately, I must take issue with two things. First, you failed to realize that I said I was interested in a permanent mount antenna and wanted to get away from the old fashioned crank model because they are too difficult for my wife and obviously, too easy to break. The Sensar you tout is a batwing antenna that must be cranked up and therefore, not in my interest to buy. By the way, if you buy a Sensor IV, it comes with a wingman included. Of course a batwing antenna is going to pull in signals from farther away; it stands taller than a permanently mounted antenna. Stating that it is,"at worst, twice the antenna the Jack is" is nothing more than opinion that hasn't been backed up by fact or specs. The fact that a taller batwing is better than a permanent mount is a tradeoff I am willing to make as long as the difference isn't drastic, and honestly, unless you can support your statement with fact, I have to believe the difference between the two isn't as drastic as you make it sound. Second, your comment earlier indicated that the poster had downgraded his equipment because "that antenna is no where near as good as the one it replaced." But in your explanation to me, you simply stated that the King Jack is not better than the batwing. Which is it? A terrible mistake, or just not any better?

Doing some research into this subject has led me to believe that for my purposes, the King Jack may be the best way to go. The Winegard Rayzor appears to be that company's answer to the Jack, but doesn't include an electronic signal finder, which in my opinion, is well worth it so you don't have to guess at which direction to point the antenna for the best results, something that you are still going to have to do with a batwing antenna. The only possible drawback for some people may be the height of other rooftop equipment on their RV that is in close proximity to the antenna that may block signals for a particular quadrant. Since I have basement a/c and no vents close by that stand taller than the antenna, I won't have that problem.

I am well aware that HD can be picked up by any antenna. However, this antenna picks up analog signals easier than digital and its UHF capabilities are not as good as some of the new ones on the market today, which is where many of the HD signals reside now. I thought I was getting a decent picture on my 40" television that had been installed by the previous owner of the coach but wondered if it was as good as the one I got in the house. OTA HD is almost always better than cable or satellite, but this one didn't seem as bright, clear or sharp. I found out just what I was missing when I stayed at a campground this past vacation that had upgraded their cable system and was offering nothing but HD service. The television came to life and looked just as good, possibly better, than the ones in my house. That told me the antenna wasn't doing its job. So when I say the antenna can't get HD, it really can't get a signal strong enough to provide an adequate HD picture. A lot of it depends on how far away you are from the transmitter and most campgrounds aren't next door to the station's parking lot.
 
OH and I missed the part about "not able to get HDTV"

I have the older technology and am watching HDTV over the air as I type.

The antenna is a radio antenna (Television is a special case of Radio think radio with moving pictures)

IN the old days of ANALOG Tv  the stations broadcasts on  specific channels. numbered originally 1-13m then they dropped 1 and went to 2-13, then they added UHF 14-83 then dropped the higher end so we had UHF 14-69,,  Thus they settled on 2-69  Each chabnel is specified by FCC rules.

Thus the antennas were deisigned to pick up either 2-69 or, if old enough 2-83

Well with the chanbge to digital ,, from the view point of the antenna, ,Not many stations in VHF and in the VHF-Lo (2-6) I think there are only a few remainnig nation wide if any Many noved to UHF for reasons technbical I wont' go intot.  BUT THEY ARE STILL THE SAME BROADCAST CHANNELS.,

The difference.. Well where I am now 12 is still on 12..  But if I move about 2 miles I get different stations (Detroit collection) wher 2-1 2-2 and 2-3 (Chabnnels 2) are actually on broadcasting on the old Channel 7,,, Channels 7 noved to 40 sonething (I think 41)  UHF stations also moved frequency some up some down.  YOu (normnally) Do not need to know the actual carrier frequency (Broadcast channel) as the TV figures it out when you SCAN FOR CHANNELS.. but you do need if you use a Sensar Pro like I do,,  But again the SENSAR PRO gives you the primary (Strongest) then you can scan and ask the TV for what other broadcast channels to search. I peak on one of the lower strength signals here
 
However, this antenna picks up analog signals easier than digital

That's impossible, since there is no difference between analog and digital at the antenna. It's all radio waves, which are inherently analog anyway. Onloy the tv tuner can tell the difference.  Perhaps what you are experiencing is poor UHF reception. With the changeover to digital tv, many VHF channels were moved to a UHF band, even though they retain their VHF channel designation. If that "digital signal" happens to be on a UHF band, you may get no or poor signal.
 
The television came to life and looked just as good, possibly better, than the ones in my house. That told me the antenna wasn't doing its job. So when I say the antenna can't get HD, it really can't get a signal strong enough to provide an adequate HD picture. A lot of it depends on how far away you are from the transmitter and most campgrounds aren't next door to the station's parking lot.

And this is why John From Detroit said the batwing (with wingman) is better, since it is directional, in addition to being a little higher, and therefore will (if you rotate it) pick up weaker signals than the omni-directional ones will. However, since you have ruled out the crankup type (they can be electrified), you're stuck with an omni, thus  you'll have a shorter range than would be possible with the other type. If you just put the batwing up without rotating it, however, it will only get good signals if it happens to be pointing at the station, when the station isn't near.

In other words, the better performance of the batwing isn't (mostly) because of height, it's because it's directional, which works better (when aimed) with weak signals.  It's always a trade-off. The height is mostly needed for clearance on the roof to avoid hitting air conditioners and such when rotating the antenna. And, of course, Gary is right on (as usual) about VHF vs. UHF being part of your problem.

So it seems you've decided that having no action needed for the antenna is your desired trade-off -- that's fine once you understand the results of your choice. Hopefully it's more clear now.
 
One thing that I am experiencing with the Jack antenna is poor or no reception when our motor home is parked so that the front air conditioner is in direct line to the TV transmitters. If I turn the motor home around and park in the exact same spot, I get good reception. I thought that the Jack antenna was a problem and had a technician look at it. He suggested that the air conditioner was the problem and suggest turning the motor home around. Since the Jack cannot be raised and I need to park with the utilities on the proper side, we just live with questionable reception on a single channel.
