Six weeks ago, a 30+ year old KLM antenna (2M-14C) arrived at the Antenna Garage : FREE After 30 years this classic 2 meter satellite antenna was taken down by a long-time VHF/UHF radio amateur, who is retiring and moving. The Phasing Coupling, CS-14C Harness will require a complete reconstruction (and weatherproof protection). The SO-239 single hole “D” connector within a PVC cylinder (about size of old 35mm film canister) feeds two (2) coaxial cables (75 ohm, RG-302/U) to the feedpoint of horizontal and vertical folded dipoles. A printed circuit board (2.5” x 2.5”), performs the polarization switching (RHP, LHP). That board is placed on the horizontal folded dipole (rear driven element). The bare PC board and relay were “open to the outdoor elements”. The board has been cleaned up with white vinegar. There was a 1000 pF capacitor, a diode, and an RCA jack (DC power) on that switch board. KLM used a 12 VDC Guardian 1365 relay, 1365PC-2C-12D. A New relay is shown below the 30 year old veteran. The 4:1 coaxial baluns (50 ohm, RG-142/U), placed at feedpoint of the folded dipole driven elements, appear to be OKAY. Shown here below the switching board. == Everyone needs a project, before the Snow Flies.
