Nice looking station. Don't know if that radio top-vents, but be sure it has enough cooling space around it, that looked a bit tight.
As for the GAP Titan, just be sure you understand what you are buying.
I own one and for what I expected of it, I'm quite happy.
Mine is ground mounted on a mast about 7' high and 40m and up it works great. 80m is very limited with this antenna. The takeoff angle is very low and it really is only a DX antenna on 80m. Won't work well at all for regional ragchew work. It says it isn't required to guy it, but it's far more stable guyed just above the gap section. I run mine guyed with just two lines and it makes a big difference in stabilizing it.
Raising this antenna doesn't do much for improving its performance due to its design. It works just fine ground mounted and works nicely for DX, which is what it is designed for. Might want to save the money on the Glenn Martin or use it for a beam instead.
For 80m regional, you would be a lot better off just putting up a horizontal wire antenna IMO. I run a randomly cut hunk of wire about 7' off the ground, literally tied off to a fence post and tuned with a Palstar AT1KM and it outperforms the GAP on 80m by a huge margin for regional use. It even loads up and works on 160m as well.
I'm still waiting on getting my ladder fed doublet in the air and I anticipate a major improvement over the end-fed wire I'm just killing time with now.
