6m Low Noise Preamplifier with QRO 1500W T-R Relays EME2-50EXP 50- 54MHz

50- 54MHz 6m Low Noise Preamplifier with QRO 1500W T-R Relays EME2-50EXP. Integrated high selectivity, high Q, super low loss input band pass filter to prevent overload from out-of-band signals. There are no HF 1.8- 30MHz or 2m 144- 148MHz or other high-power stations that could overload this EME2-50EXP preamplifier. 1500W legal limit relays are integrated inside EME2, including isolation relays. The extremely high-power device you always asked for.

QRO is made on low dielectric loss RT/duroid® 5880 Laminates (not on FR4, which is very important!).
