Well,,, I've looked at the G5RV and the Carolia Windom, both look "Interesting" but I'm thinking not for RV use (Too long)
I run a 75-100 foot long wire off a KAT-1 Antenna tuner with my TS-2000 (KAT=Kenwood Antenna Tuner, the KAT-1 is a MARINE grade unit, so it's mounted out in the weather which seems to bother it not at all) I've gotten lots of comment, but no complaint.
But then I tend to avoid operation during Prime Time, It's not so much avoidance as.. "Otherwise occupied" I do a net around 6-7pm and sometimes make a PSK contact (10 -40 watts of power is all) and then get involved with other things for a few hours, like the campfire, computer, Virtual Campfire, and so on By the time I get back to the radio it's past prime time.
Plus with PSK you don't overdrive the rig,, In fact you drive it till you see ALC action, then back down on the audio drive till the ALC is not doing anything, no processing, so you are running 1/2 power or less, no distortion that way, no SPLATTER
I'd really like to hang an 80 meter dipole though, or the G5RV Which just sounds like the antenna we Motor Homers should be using don't it (Pun very much intended)
