If I had the kind of bucks being poured into these, I'd think I'd go all the way and put up the 80M yagi G0EVY has.
Its comprised of actual towers welded together and has 2 66 foot elements and is like 140 or so feet long.
It weighs in at 150LBS and requires a mobile rubber tire crane to lift it to a height of 150 feet.
You could probably do this project for 100G and you'd have control over your yagi in severe weather.
It was designed by either AA4MM/AA1MM not sure on the correct callsign. LOL
