Hi Bob.

There is a pre-amp kit available over here for about $70 which gives 0.26dB noise figure and 34dB gain at 1296MHz. Without resorting to cavity designs, this sounds pretty state of the art and is been used for EME.

Thanks

David

Hello Domenico & all Thanks for all the information. The measured F/D ratio works out to 0.375, therefore a patch would be appropriate. As mentioned earlier I would be content to just be able to receive EME (for now). For transmitting no doubt a different feed would be needed. Currently I am looking around for a preamp.
