I see you settled on a firestick NGP antenna.
Be sure to go their web site and check out their FAQ
and special instructions on coax length etc.
http://www.firestik.com/Tech_Docs.htm
The firestick does not care where it is mounted as far
as a ground plane because the coax shield it it's counterpoise.
That is why it works well on fiberglass.
Firestic has some special instructions on their site you need to read.
They are not like a ground plane antenna in the coax used and lengths etc.
These are also reported to be very sensitive to tip length and the plastic
cover over the tip if yours came with one.
Make sure you use their harnesses etc.only.
They will tell you why on their site.
On my Class C I used a standard grand plane 4 ft fiberglass whip
not a Firestick, on a finder mount. I have not problems with SWR
and 1-20-40 being all under 1.3:1.
You should be able to get under 2:1 and most likely under 1.5:1
by following their problem solving instructions.
