David the one I got the previous owner just put RVT all over it, except the RCA jack. I need to redo it, but it's raining, hi. The 435 yagi came with an aluminum box enclosure....wonder why they didnt do the vhf yagi the same ?? Course we'll never know as they are out of business.

Anyone out there with KLM antennas with the polarity switch care to comment on whether you have put a housing on the switch to protect it from the elements? It looks like the relay has silicon around the base but it just grates me the wrong way to have a circuit board with a power connection and components exposed to the elements.

Maybe it has not been an issue but I'd care to hear of anyone experiences. If anyone has built up a housing and have pictures or directions, please pass them along

as I recall there were 50 some odd pounds of ballast launched with the bird...to bad it wasnt an amateur repeater.

Yeap...it is generally either concrete or lead...and the concrete is favored..something in my memory says however the ones on TDRSS were lead. somewhere I probably have a picture of the ballast being attached to the "bird". Indeed I got a letter published in both AV Leak and Navy Times (as I recall) about the ballast...and "other" payloads. I also recall the IUS upper stage carried ballast as well....to bad it wasnt an Amateur radio transponder...lots of power on TDRSS 1.

When I picked up these KLM's over in Lompoc, the fellow works at Vandenburg, and he told me that alot of the ballast is nothing but concrete !! Can you imagine all that concrete chunks out there and they know where the majority are....amazing.
