Antenna question

There might be specific caveats. 102 inch whip on fender vs a 2 foot whip on mirror....I imagine giant whip wins. @rabbiporkchop says my 4.5 foot Wilson 1000 magnet mount on the roof would beat said fender whip.

 

You would be better to mount the 3ft'er high, compared to the 4ft'er low

 

I think it all depends on how it is attached to the vehicle.
I would generally prefer to run a shorter antenna mounted to a higher location

 

I agree.. im thinkin of w.coast style mirrors as an example. A 3ft on the top bar..waaay better than a 4ft on the bottom bar

 

As tall as possible is better...Im learning that the feed point(where coax connects to ant)is supposed to be at basically your grounding point(where antenna is mounted)....
A 4 foot is better than 3 ft of same ant type..A 5 is netter than 4 ect ect...Supposed to be easier to tune and more efficient makeing it easier on the radio and better tx/rec..

 

Keep it as tall as you can..as long as you clear 13'6" your good unless you are in places that have only 12' clearences..
A taller ant set up is more efficient and easier on the radio and helps it get out further..Doesnt add power to radio or nothing..Think of it as a short ant being in a vally or on top of the only hill in the world....Go as tall as you can but stay onder your height limitations..

 

We used to say height is might but if you're only talking about 5 feet you honestly can take your pick.
