what are the differant antennas all for?

[BigNormitasca]

So ive got 3 antennas that came with my 76 itasca.  One antenna looks like a boomerang, i used to see them on the trunks of limousines.  The second antenna is standard straight antenna thats about 3 feet long.  (I already have a radio antenna sticking out of the hood so i dont think this is what that is.) and the last antenna is straight but its 7 feet long.  They all have threaded bases that attach to a mounting point on the roof.  Anyone know what each one does?

Can you post pictures of these antennas? That would help us know what they are for.

The boomerang is for the TV, the 7 ft. whip is a CB antenna and the 3 ft. antenna is for an AM/FM radio.  Do you have a second radio/entertainment center besides the one in the dash?

The Boomrang sounds like the King Congrols JACK TV antanna. Not the best by a at least half.

Other antennas. Dash radio, (AM/FM) and CB are common on RVs  YOu may also have a GPS or Sat-Radio antenna but they look more like a bump on the roof.

ON my RV the AM/FM for the sash is a stupid little rubber covered spring about a foot long give or take. next to worthelss less than 1/4 the range of the 21" whip on my car. 21" w/o coils (other than possible a spring at the base) is AM'FM as I recall. about 3/4 of a meter long. (75CM) I am afraid inch/cm is one conversion I don't do in my head.

Cb can be anything from about a 1' spring covered in rubber to several feet to 11 feet long. But all but 11 feet are going to be a spring covered in rubber or a fiberglass stick wound with wire.

John, I suspect you are thinking "11 meter band" but a CB ? wave antenna is 108", or 9 ft. Channel 19 wavelength is actually 434.357182269634 inches, or about 36 feet.
