Hi Steve - I just purchased a DX-77 just yesterday. It's still in the 
box. I was looking for a simple antenna for the second radio, to permit 
SO2R and M/S operation.
I asked the same question recently, and also reviewed the archives of 
 I wanted a vertical that did NOT have 80m coverage, as it will 
be placed about 150 ft from the tower.  This is only 1/2 (plus or 
minus) wavelength on 80, and I didn't want interactions with my 80m 
slopers. I believe the GAP has 80m, so I ruled it out. I also ruled out 
the GAP as there's one in the neighborhhod here, and it bent after a 
storm when everything else survived unscathed. I got several reports 
that it's too easy to fry the traps in the R7000 (unlike earlier 
Cushcrafts like the R5 and R7). One RTTYer told me he fried a trap at 
500 W. That left the Hygain, which got some decent reports, and no 
negatives I'm aware of.  Also, it does not require radials, and is 
suggested to be mounted on an 8 ft mast, per Roger Cox.

On another note, the coax for the vertical will run in the ground for 
about 150 ft, until it joins up with the tower and my other cables, and 
then runs in conduit to the shack. What are the current recommendations 
for RG8-style coax that can be directly buried? Any sense in putting 
the buried portion in a garden hose as added protection?
