Does this ring a bell with anybody? Id really like top find it again.
I would be highly directional and narrow in the direction of the far end of the wire though.
I believe Cebik covered end fed wires. That's the site you want for wire antenna info.
it really sounded like something when I read it
QRN, Are you sure you measured the length of your wire properly? I didn't know Canucks knew how to measure in feet
Actually i grew up with the standard system and learned metric in middle school so it's real easy. Measuring in Smoots however takes a bit getting used too.
It is possible
However, you will use 450 ohm antenna and a 4:1 balun and a radio with an Antenna Tuner or a Linked Coupler tuner. I know it will have much gain but again very directional and not a lot of usage.
Do as someone else suggested in the posts. Read L.B. Cebiks years of research at Introduction
Check out the DOUBLET instead at cebik.com. It will not have quite as much gain but it is high gain if you make it 140 feet or even 280 feet if you have enough yard or trees. Again you will need ladder line a 4 to 1 balun and an antenna tuner
Savoir Faire is everywhere (Wheeeeeeee)
That's not possible.
According to an EZNEC 5.0+ Pro model I just made the gain at ten feet above the ground on 14MHz is 8.5 dBi. At 200 feet it's 11.1 dBi.
What you described is a Beverage antenna. They actually have little gain and are not used for transmitting. They do however have a sharp frontal lobe at the terminated end. They are very low noise antennas and are usually used with a preamp.
They have to be several wavelengths long to be effective.

You don't transmit with a Beverage antenna; they're for receiving only. (Well, okay, you COULD transmit with one, but not well at all. Make the worms nice and toasty, though.)
