Hi Garry, Happy New Year!
The summit itself is rocky and not suitable for guys. There are also too many people around for a safe HF activation using a traditional HF wire antenna. 2m FM activation using a hand held is easy from there. Some have activated HF from the grassy side slopes using bushes as shelter and to get a little privacy.
I’ve done it twice now, as detailed in this thread. Further down I explain how I got around the guy problem.
A Micro-Adventure (or Urban Mountaineering) on GM/SS-272
Good Luck!
