I've got a 6ft steel fence post that I could add onto my telescopic 20ft antenna mast...it would basically add 5ft to the height, taking the top of the antenna from 23.5ft to 28.5ft.
Would adding 5ft even be worth it? I could spend $25 on a 10ft steel post, but I figured since I already have a 6ft section laying around, I should try that first. But would it really make much of a difference at all?
For reference, I can hit a repeater about 30 miles out, and simplex clearly out to about 12 miles and I start to get a bit of static after that, with no reception at all at about 18 miles. Compared to the area I'm in, my antenna is in a bit of a low spot.
