[VHFcontesting] 2m FM LNAs?

[Jeffrey Guenther]

Everyone,
Not a skilled 2 meter weak signal nor FM operator.  I have a TE systems amp which I use for both modes.  Also have an Advanced Receiver Research pre-amp in the shack.  I have heard mast mounted pre-amps are the way to go.  I would say both my pre-amps make a neglecable difference.  Yes, they amplify the noise equally as well as the signal.
I used to have an RF Concept amp in the car for FM simplex work with a 5/8 wave supposedly gain antenna.  It made for fun communication on simplex.  Some could hear me and some couldn't.  
If you are using the radio in your car get the best vertical antenna you can buy and settle for that. For me that was the   Diamond NR22L monoband vertical antenna. The most important thing for
 VHF is height of the antenna.  You just do not have that with a car unless you are top of some hill.
