BT-75 Beverage Transformer

Click to Enlarge Beverage receive antennas, even short ones, can make all the difference on the low bands. The BT-75 Beverage transformer is your first step in building a wire Beverage antenna that really pulls weak DX signals out of the noise.

The BT-75 impedance transformer uses separate windings on a binocular ferrite core. The output is designed to match low loss 75 ohm RG-6 CATV coax for maximum performance at the lowest cost.

Designed for long term reliability, the electronics are are housed in a NEMA rated enclosure and use stainless hardware. A gas discharge tube gives added protection from nearby lightning strikes. Inside, the components are given a coat of electronic conformal coating for added protection.

Installation is simplified with mounting flanges on the case. Stainless steel wing nuts make antenna and ground wire attachment in the field a quick process.

Complete your Beverage antenna system with the RXT-470 termination resistor, sold separately. The RXT-470 uses a 470 ohm ceramic resistor featuring low inductance, high surge capability, and is rated at 2 watts. It includes a gas discharge tube for extra protection and is housed in a NEMA rated case.
