2m Ultimate Transmit-Receive Relay Switches BPF VLNA EME2-144EXP 144-148MHz

A Complete Solution for contesting, DX-ing, and Moon bounce – EME. 2m Ultimate Transmit-Receive Relay Switches BPF VLNA EME2-144EXP. Full frequency range 144-148MHz with maximum power 1500W. 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, 6m 50-54MHz, or 70cm 430-450MHz stations that could overload this EME2-144EXP preamplifier. 1500W legal limit relays are integrated inside the 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)
