VHF-UHF-LNB Bias Tee in enclosure

wiki order

This is universal VHF/UHF/LNB Bias Tee box. Designed for Low Noise Amplifiers, buffer amps, LNB etc. Including protections at RF and also DC path. Variable Attenuator allows you to reduce signal when LNB or preamp has to high gain. RF limiter and resetable fuse protects against strong signals (transmitting into device). LED indicators show DC voltage ON and also when the voltage is over 18 V, LED indicates it. In the case of LNB it means switching from V-pol to H-pol.

Unlike other Bias Tees on the market, it includes an RF limiter to protect your RX from strong signals.
