Re: DEM downconverter



Joe:

DEM indicates you can order an optional crystal for the 2446 band when it
its activated (note the optimism).

I've not seen a Conifer, but I think the Philips is a first-class unit.
It boasts a true gain of 24dBi, and can be mounted for horizontal or
vertical polarization.
