I like the lower band UHF 9.5 myself, it really rocks and is pervasive with the signal in digital too. Yeah those towers belonged to my neighbor Sonny who died from lymphoma, he sold his front yard but they're not electrical but do cause a problem to the West where a few major VHF stations are. The 9.5" sorts it fine; I keep it towards the East in Lousianna where theres a ton of Fox stations.
I surveyed my place and thought If I had a cherry picker I could nail a version into a tree, but simpler is to U-Bolt it to a roof vent and run a short coaxial into the room. I'm wondering how long a balun would last in the baking sun, or if the metal would rust soon, or copper turn green, but that would be a high, clear area.There must be a good conductive coating for the finished model they use.
Its only logical to exert energy on duplicates of good models to make 8 bays, at least the db and gain should be significantly higher on an 8 bay but havent learned the computer models on it. For convenience keeping it near the ground isnt too bad in my area until I see a station is worth grasping for then Ill go up to the roof. I guess theyll be some minor changes. In Dallas with a rooftop VHF I used to get tons of stuff.
Building a good model like the 9.5 " is a keeper, cause any storm out here could obliterate a commercial antenna in one day. Oh well If you get too bored make the Lord Kelvin water drop charger; it makes electricty easy.
