Homebrew Double Zepp Antennas
Posted bypenghulu on Tuesday, November 13 @ 11:04:04 MYT
Contributed by penghulu

Antenna has been improved with removable radials for easier transport and cheaper shipping, This makes it an Excellent ARES/RACES Antenna.


9-10dbi Gain on 440
6.8dbi gain on 2 meters

Antenna is a full Wave on 440 and almost a full wave on 2 meters.

All Copper 2 meter / 440 N2RGA Extended Double Zepp Antenna.

All antenna's are individually tuned for a SWR of 1.2.1 on 444 MHz. On 2 Meters I get a 1.3.1 SWR.

All antenna's are fully assembled ready to install onto a Piece of PVC pipe.


Antenna is 36" x 20" x 1/2" copper pipe.

Why pay $150 for that 27 Foot monster antenna.

Design is 10 db gain on 440 MHz and 6.8 db Gain on 2 Meters

Works great for an apartment (condo) or on top of your roof. Also it's great for field day or an Emergency Antenna.
