2 meter XPOL EME Yagi Antenna 14 + 14 Elements 2m28XPOL


SKU: 1010 Categories: ,

2 meter 28 elements superior G/T EME XPOL antenna 2m28XPOL

Extreme gain for super weak EME – Q65 MAP65 signals on 144 MHz band. Highest possible suppression of all side lobes and the best G/T for antenna length.


100 W with this 2 meter XPOL antenna is enough to work many EME stations

Look at famous VE7BQH table:

Press “VE7BQH 144 MHz Tables” ROW 256 and 257. Or search “PA144”

One of the best performing antennas on the table for its sizes.

One of the most important parameter in the “X” or “+” configuration of antennas is coupling.

We have measured it on this 2m28XPOL.  Just excellent:


Measured Coupling PA144-XPOL-28-9BGP CXPOL Antenna


Better than -35 dB in the prime part of 2m band. Which is more than sufficient for any purpose.

We consider that mechanical construction is even more important than electrical parameters. That will lead to many years of trouble free operation.
