extended double zepp for 11m

[Uncle Ronnie 336]

gave it a whirl flatside from the east coast hoping to net more contacts west of the rockies. the gain and radiation pattern is tight so using a geodesics tool and figuring out what local city i have to go broadside to, I got 2 trees picked out and hucked a nylon rope over the branches about 20' up. now CT to CA is easy. highly recommended cheap gain for the blue collar man on a budget.
as a bonus there are SWR dips down to about 13 mhz and it works as a SWL antenna for anything above 40meters.

Hello UR336: That sounds like a neat project. How are to feeding - matching it to the twin lead. Antennas Tuner? Do Tell please.

so each leg is 5/8~ and the ladder line IS the matcher. about 3/8~ is a 50 ohm point and thats what you trim to get the SWR down before simply feeding it with a 1;1 or coax choke. no tuner needed for just 11m

Below is how I made mine, I am still using it these days !
It does an excellent job and is hard to beat as a vertical.
Perhaps the link below is useful..
Kind regards,

nice, yea i had a similar one, just with 2 1/2 wave legs as a vertical before. def was a good one. that one got replaced by an imax about 20' higher and i really don't notice much difference other than the fact that i can hear a distant electric fence ticker now

after using it for a bit, i can say YES BUILD ONE
getting west of the rockies from new england was a challenge before, seemed like people in texas and the midwest were blockin me out when i was tryin to shoot that evening skip. now im right up there with em all for a piece of ladder line and a split apart speaker wire.
