I am looking for some advice on LNA VHF preamps from the VHF+ gurus that subscribe to the list. I am not an EE nor do I even try to play one on TV and I certainly didn't stay at a Holiday Inn Express last night, so I am looking for some education on this subject.
I have been looking at several LNA designs (specifically for 6m) and it seems that they come in several flavors. 1.) dual gate MOS FETs 2.) GaAs FETs 3.) bipolar transistors One mfg. claims that the new "very low noise" dual gate MOS FETs have a better noise figure than the GaAs FETs. I have always heard that the GaAs FETs were the way to go for the best noise figure, so I am confused from the marketing hype. I am looking to get a non-mast mounted preamp for 6 meters. I have a few transceivers that cover 6 meters, but are not the best for weak signal work and need a little help. This could be a receive only device, as that would be it's initial function, but I am not excluding mast mounted ones either. If anyone want to make a recommendation for a particular mfg. or kit, that would be appreciated too. -Tim, W4TME ---- -------------- next part -------------- An HTML attachment was scrubbed...
