Strange thing happened today

Hey guys I got a little baffled today and for the life of me I can not figure it out.....
I am running a 4' wilson silverload mounted in the stake hole of my truck.
So I thought today I would put another 4' wilson in the other stake hole just for looks and not hook it up....well when I got it hooked up I figured I would just check my SWR to make sure ET was ok....and it was through the roof.....I adjusted a little on it made sure all my grounds were getting a good conection and everything was A OK.....so then I thought the antenna was bad so I switched it out with the antenna that wasnt hook up and swr was just right .....1.3 on 1 and 40 ....cool I got it fixed right? but the other antenna back on the other stake hole and guess what ...through the roof agian so I just said the hell with it and took the one not hooked up off....So what would cause this ? it isnt a big deal I was just trying to get the even look with the dummy antenna .......I was pretty aggervated by the time I figured out what was going on :lol:

Very Strange since the dummy wasn't even hooked up to anything.

Yeah the only thing I can figure is that where the washer was missing it was grounded and the other antenna was reading it for some reason ....or I may have bigger problems and not know it


I have stake hole mounts with a 8ga ground wire from frame to mount...then the little wire on antenna to mount.....without the little wire hooked up I have terrible SWR
SWR Ch 1 ---1.3
ch19 ----needle doesnt move
ch 40 ----1.3

What happened was. With the washer off, it was acting as a "1-hot, and one not" set-up. Generally see guys do this on Suburbans. They will have the front antenna hooked up to the coax, and the back one not. This makes the rear antenna a reflector antenna. You would have to reset your swr in order to run that type of set-up, by adjusting both antennas...

On a Suburban, this would give you a more directional signal out the front of the truck. Off yours however, would direct the signal to the side! (not good) :wink:

Do not argue with an idiot. He will drag you down to his level and beat you with experience.
