You can also feed a 1/4 wave wire with the feed point grounded to one leg of a piece of 450 ohm window line and then short the bottom end of the window line at the appropriate length to make an eleva

That's not really a J-Pole.  A J-Pole generally has a 1/2 wave vertical section, not a 1/4 wave.  Since the end of a half wave is high impedance, the ladder line is used to get a match.  If you only

Just want to reiterate that John and Jim both speak the truth. Years ago I used to cart an old GAP vertical dipole down to the Texas coastal islands every year for the IOTA contest. The difference in

Those pine trees would suck up a lot of the RF from the vertical, but likely far less with the horizontal antennas. That's been my experience in my very dense redwood forest, and I've heard that pine
