A Dipole for your CB Base Station?

[Watergate]

Half of 11 meters for the positive element and vice versa for the negative.

Google Double Extended Zepp. That should give you an idea of how difficult matching is on the full wave dipole.

If a 102" stainless steel whip plus the 1" mount is used for the positive element and the shield of the feeder coax is used for the negative element with a RF Isolator mounted at the 102" point then that could be used as a dipole.

make a quick one and try it out, havent heard of anyone doing that,, and usually there is a reason. but thats all part of the fun , trying something. its only a dipole if it doesnt work you can always cut it down to the standard dipole length. if it wasnt 4*f outside here id go try it just for something to do

I've read that I would have a high SWR (10:1)trying to do that using coax and not a ladder line or a matching network at the receiver.

the radiated RF is not DC,...... the "pos" and "neg" (dare I say) alternate

Yea,I just found that out reading another forum.

Pulsating DC????

The one that the center conductor is hooked too I refer to as the positive. And yes,I'm getting used to the phraseology.

you should make something like these guys are using, scroll down to the 2nd vid and they have a close up of their antenna, looks pretty basic , man it was sounding good here today for over 8000 miles away!

an antenna with pulsating DC MODULATED audio............ what an advertizing concept

That is an idea, say the matching network is actually a step up impedance transformer that amplifies pulsating DC audio.

Shit I will contact Jo-Gunn and be a marketing rep for them.:

I don't think my iPhone will play that

Why not two 108" or 102" whips

It's been done for years.

If you can build a dipole you can build the skyper or bird yagi mentioned above. Great antenna. In fact the 2 element version( bird jungle job) is even easier to build . Look up Dick bird G4zu. R.I.P

 

[vkrules]

Yes if you have them why not? If you don't it's a lot cheaper ,and just as easy to make a dipole.Often wondered why people go out and buy 2 commercial whips and mounts just to make a dipole for home use.( portable I can see the appeal)
