Dual Whips

Hello Everyone. I'm looking for some info on hooking up dual whip antennas. I have a 88YJ that I'm trying to get the old school Military look and want to use the dual whips. Dose anyone have a wiring diagram or can maybe point me in the right direction. Also has anyone else ever done this and if so how did it work out for you? Thanks in advance for any help...Gunny Out!!

Well in the old days I would have said go to Radio Shack, but I don't know if they can help you or not. I would say talk to some of the commo guys if you are in the Camp LeJeune Area

Many years ago I ran dual whips on a CB. As far as wiring goes, it was just a "Y" connector in the antenna wire. Now the SWR tuning and getting benefits from the 2 antenna is more of a challenge. Most 18 wheeelers run 2 so it is common. I would start by finding a truck stop that installs CBs for parts and advice.

You won't be able to get the antennas far enough apart on a Wrangler for them to work well as a dual whip antenna, 9' apart is the optimal distance apart so they work well together. I would make the second antenna a dummy and strictly for looks.

as stated you need some space between the two whips..
you can find the dual coax specifically for dual antennas at either a truck stop.. most of the bigger ones carry it and or a radio shop can at least order it for you.. or check amazon... or something like that..

I ram dual whips on my M38A1 but only ran one for CB and one for radio... still looks totally cool.

Truckers mess around with duel antenna systems for 2 reasons... well 3 if you count 'looks'

A) It gets rid of the "Shadow" caused by the big metal box they are pulling..getting signal on both sides of the rig. A total NON ISSUE for a little Jeep.

B) If done right it gets them gain strait ahead and strait behind them.. at the cost of performance to their right and left. Great for talking down a strait highway but may not be what your after on a twisty trail.

And like others have pointed it wont work right unless you get them at 9' apart.

And if your going to try it anyways you need a special "Co-phase" Y cable. You cant just use a T connector and normal CB antenna cable. The dual system needs 75ohm (RG59 or RG6) coax... With out that it will never tune.
