I was wondering about the bottom load vs center/top on the roof top. I've been experimenting with a bottom load roof mount Wilson, 102+spring and a 7foot firestick on the roof of my 4Runner. It seem like the bottom load works better on the roof. Is this normal? And if so why?yes,,, what do you need to know? i have used in the past,, a/s big mama turner signalkickers have even mounted 102 inch whip on trunk mounts,,,, i have tried k 40s and all kinds of fiberglass whips,,,,they all do what you want them to do, but with varying degrees of preformance,,,,, the best antenna to have on a trunk mount situation is something center or top loaded.... if you go to roof bottom will work better but on trunk it has always been better center or top loaded,,,once on a pontiac i had a few years ago i run a wilson 2000 trucker that out did a wilson 5000 both mounted on trunk lid,,,,
derek,, it has a lot to do with the roof line,,, when the coil is bottom and on roof it is very efficient for what it is,,, on trunk mounts the coil centered or top is more efficient than a base coil,,,the same goes for putting a antenna on bed of truck,,, a base load not very good on bed but a center/top load will be more efficative,,,,,,
