I have seen them tripod mounted but wonder why (it was only about 4 feet off the ground)
Is this a TT or a 5ER
on a TT do a front mount.. on the Tongue clamp a piece of pipe.. This can be a short length of TV mast or any pipe of the proper size to fint either inside or accept the small end of a TV mast (I'd use the last 2 feet of a TV mast)
Now you can slap 10 or even 20 feet on top of that when parked
When "on the road" coil the Coax up antenna attached and store in the front compartment.. (This is often done by hams by the way) I'm not sure how much I'd like puttin it up 20 feet but shold work
I use a flag pole. park on base originally till I destroyed the base Now I rigged something a bit different.
Some 5ers you can extend the frame rail and do the same mast thing. Or a 2" receiver and a hitch adapter mounted piece of pipe.
