LNA BFG135a 144MHz

We need better RX in OK2M, for season 2009 i draw PCB for LNA, bypass relays, attenuator, power splitter. LNA is YU1AW design. It works perfect for us. Gain is about 16.2dB (after attenuator 3,16dB and 3dB power splitter). I build 6 LNAs and all works same, in first i use CuAg wire, but for others i use Varnished copper wire dia.0,8mm, gain is same, noise figure still not measured.
