Another Multi-band Dipole

Mark - W5EZY
I recently built an 80/40 meter half-wave dipole using
the small 300 ohm ladder line, and it works very well.
 This design is very light, easy to install and makes
for a very clean looking antenna.  Mine is in an
inverted V configuration with the center at about 55
feet.  Wonder if others have tried this antenna.

This is basically a center fed ZEPP.  When I was at T30NN and 3D2NN I used a center fed ZEPP which consisted of a 44 foot piece of 300 ohm TV lead-in for the feed line and the horizontal parts were stranded #18 wire each side being 23 feet.  Using the K2/100 and KAT100 this antenna tuned 80m-10m with 1.0-1 vswr.  The antenna center height was at 17 feet, supported by a fiber glass extending twist/lock pole from SteppIR antennas.  Each end was held up by a 15 foot fiber glass extending twist/lock fishing pole from Walmart.  See, sometimes when on a remote place there are no trees to support an antenna, so you carry your own fiberglass poles.  I worked many, many stateside and EU stations with this portable antenna.

Joe and all,

That is my favorite portable antenna too.  In a pinch you don't need 3
supports, 1 will do to hold up the center.  The 2 antenna wires and the
feedline CAN also be used as part of the guys to hold the center pole
upright and you have an inverted VEE - OR with one half of the antenna
positioned along the pole you create a vertical (leave the excess wire at
the top dangle or tie a line to it to make sort of like an inverted L - the
higher current is at the bottom anyway) then run the other side along the
ground as a radial - yes in this vertical case it would be good to have
another length of 23 foot wire to add as a second radial running in the
opposite direction from the first to cancel the high angle radiation -
better low angle radiation if you are searching for DX rather than locals.

73,
Don W3FPR
