KLM 2M-22C antennas

[Don Meyer]

I came across a pair of these KLM 2M-22C cross-polarized 22 element 2M antennas. They are new in the box. I opened the boxes to verify that they were in fact complete and never assembled. A similar M Suqares version of these is about $600.00. I would ship them both for $550.00 or make them available for pickup in either Mt. Vernon or Bellingham for $500.00. I thought I would offer them locally prior to putting them on QTH of EBay. For further information please contact Don, N7BT. 360-319-2319

Just a note on the KLM-22C.

I have one that I made as a single 11-element yagi, then used the extra eleven elements with a second boom to make another 11-element yagi.  I have mounted at 45 foot stacked 12.5 feet apart in vertical polarity for really nice terrestrial antenna for FM/SSB.  Each antenna is rated at 13-dBd or 15.215 dBi.  I conservatively rate two stacked at 17 dBi (slightly understacked).  In photo they are two attached at top of crossbeam; larger antenna are my 6m LFA 7-element: dec_1_2018_6m_array_2.jpg (960×720) (kl7uw.com)

For satellite they are well over-rated, or if you bought two they might be used a x-yagis for eme (not connected for circular pol).
The antennas are designed for full 2m band coverage so 146-MHz has the best SWR.  But one can tweak the spacing of the folded-dipole driven element to adjust that a tad.

Good value, nice antennas.

Slight math error.  dBi is 2.15 dB higher than dBd, so 13 dBd = 15.15 dBi.
