Here's the location for my proposed topband antenna. The land plot is 23x21 meters, level ground, and as yet with no buildings on it. But it will be used to locate a single-storey hotel, basically consisting of guest rooms around the perimeter of the land, and a small garden and swimming pool in the middle.
At one edge of the plot, I'll locate a water tower, maximum of 15 meters in height, atop which I can afix a small HF beam, a VHF beam, and a Wellbrook loop antenna. Here's the height issue. My land plot is only 400 meters from the runway of Phuket International Airport, Thailand. It's of course, an airport hotel, and I'm parallel to the runway, (so noise is actually not so bad). But 15 meters is my height limit for all buildings and antennas, since the pilots complain otherwise when they get tangled with my antenna wire :) Any ideas for a top band ax? If it helps, I can lay down a 'mat' ground plane right across the land plot before I construct my buildings. My power limit will be 100 watts and I want to use topband for DX contacts, not local rag-chewing. 80 meter operation would also be a bonus... . The water tower cannot be centered in the land plot. I could possibly erect wire antenna supporting towers at each corner of the plot. I could load the water tower, use the HF beams as a top hat, and then run a horizontal or sloper? If you want to see the QTH on Google Earth, (complete with plane landing on the runway), check out: 8 6' 31" N, 98 18' 38" E Thanks for any suggestions Simon - HS0ZIB _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
