I had the only the 2m elements of my Arrow attached to the crossboom
of my B5400 az-el system and it worked fine. I suspect that if you
set it at a fixed elevation angle and rotate in azimuth it will work
pretty good for satellites. The 6-element 432 antenna will be a bit
narrower in beam, but I suspect still would work well.
One issue with permanent mounting is the elements get vibrated loose
by the wind and fall off. If you can find some star locking washers
to slip on the threaded element ends that may help. I have also used
my Arrow for VHF/UHF roving with my truck. Also, you are stuck with
one polarity and may experience some fading as the satellite polarity shifts.
The Arrow should work with any radio. If it is a dual-band radio
with one antenna connection you must use the diplexer (limited to
low-power). If there are separate antenna connectors on the radio,
run two separate coax lines to the 2m and 70cm antenna feeds without
using the diplexer.
I took my FT-817 and the 2m 3-element Arrow antenna to a 3300-foot
mountain top and worked 206 miles tropo on QRP 2m SSB. Nice travel
