Hi all you Antenna Elmers out there--
Antenna design question for you-
How can I build a low-profile high-performance antenna for mounting on a truck roof rack?
Lower than 1/4 wave high from the rooftop...
I have a midsize pickup truck - a Nissan Frontier crew cab with a full size roof racks on it.
I have a 2 meter rig in the truck, and a fold-over MFJ-1422 on the roof.http://www.mfjenterprises.com/Product.php?productid=MFJ-1422
In the course of my work, I'm in and out of parking decks all the time
and I'm always folding the thing over, or sometimes not bothering and just
not being on the air for days at a time.
I've tried a 1/4 wave (also MFJ) on the roof, and
since I live in the mountains, performance is a good bit less than optimal.
There's a significant difference in how I make repeaters between
a 1/2 wave and a 1/4 wave...
Obviously, the best thing is simply more metal in the air.
The only thing I can think of to do is to find some
low profile but multiple elements design.
I'm happy to drill/mount whatever on the roof rack. Truck has 126k miles, so I'm not looking for something perfect.
I've heard that mounting an antenna on the bed, say in one of the stake-holes or the hitch
would work, but has some downsides when the repeater is through the cab in front of the truck, and half or more
of the antenna is blocked.
So I'd like to find a roof-top solution, if there is one.
Can I feed four 1/4 wave verticals mounted onto the roof rack?
