It really depends on where he's located.
In the city, where there's a lot of high power
RF floating around, the discone would be a
better choice. But in the countryside, away from
any high power paging systems and public
service transmitters, the Terk might be the best
choice. I used to use a mast mount TV amp when
I lived in a sparsely populated area and it worked
great. When I moved closer to the city, I got nothing
but desense and intermod. YMMV
