Denis VK6FADF lets us know that a bit more digging (keywords are everything!!) turns up the following for anyone interested... A home-brew duplexer (microduplexer) here, with reference to the Arrow site following... The above refers to a PCB which can be homebrewed or obtained commercially for US$3.50 from Far Circuits Arrow Antennas site lists their commercial diplexer for 10W rating for around US$60 (plus shipping?) I would be keen to combine (no pun) the duplexer with a couple of yagi's produced to the VK5DJ yagi calculator as demo'e to the Group by Terry VK6ZLT at last meeting. I'd be inclined to use a larger number of elements (than the Arrow) in each yagi for better gain while still allowing for reasonable portability. #satellite #antennas #suppliers #vk6fadf |
