Height ... 65-70 ft. thanks to a very tall sycamore tree. An equally tall maple is also on standby should the need for a second support structure arise.Originally Posted by n0eq
That's a nice, high dipole. I'd like to hear more, please.
Length? All flattop or inv V/dropped ends etc?
Feedline type (Ladder etc)? Distance to radio?
Any special tricks in getting the feedline into the shack
(assuming your shack is inside)?

Length ... cut for 80 meters
Style. ... Inverted Vee design. Property is too small to run full length flattop.
Feedline ... Insulated balanced (open wire) line.
Length into shack... approx 70-75 feet. Shack is on 2nd floor so that gives me about 15 feet above ground. Line reaches in with excess to spare.
Point of entry... Currently enters through side louvers on an air conditioner. But soon will enter via feed through insulators in attic window.
Tuner... A Johnson 250 watt link coupled "Matchbox" tuner.
Usable bands... Antenna can be tuned for 75, 40, 20 and even 10 meters. Most efficient on 75 and 40, but pretty good on 20 as well. I have had limited success on 160 meters by tying the ends of the balanced feed line together and running it as a random length wire against a ground. I also almost smoked a network hub trying to run it on 160.
Grounding system... heavy gauge braided copper rope tied to buried rod. Good electrical ground... decent RF ground... probably not a good lightning ground. (Hopefully we'll never have to test that last property).
Incidents... Have heard the feed line/tuner arc & crackle during nearby lightening strikes.
