RM Italy 27/586 TVI Filter Low-Pass, 0–30 MHz, 500W, SO-239

The RM Italy 27/586 is a low-pass TVI (Television Interference) filter designed to suppress harmonic and spurious emissions above 30 MHz from HF and CB radio transmitters. By passing signals up to 30 MHz with minimal loss while attenuating everything above — including VHF and UHF TV frequencies — it helps prevent interference to television reception caused by transmitter harmonics.

Rated at 500W and fitted with SO-239 sockets on both input and output, it connects in-line between your transceiver and antenna with no modification required. A straightforward solution for operators experiencing TVI complaints or operating near sensitive TV reception equipment.
