Panorama DBLC-TET-N TETRA UHF Branch Line Combiner

Panorama DBLC-TET-N TETRA Branch Line Antenna Combiner, 380 to 430 MHz UHF range

The DBLC-TET-N from Panorama Antennas combines two TETRA (Terrestrial Trunked Radio) mobile radios to the same antenna. When you can only fit one antenna on a vehicle, for example, then this combiner is an excellent solution. It provides greater than 26 dB of isolation over the 380 to 430 MHz UHF range, low insertion loss, and an antenna match at 1.2:1. It can also connect two antennas to a single radio.

The isolation provided by the combiner is dependent on the antenna’s VSWR. An antenna match of 1.5:1 VSWR will result in a reduction of isolation to 20 dB. Higher VSWR on the antenna port will result in a further reduction in isolation between the TX ports. During operation, extreme care should be taken to ensure that the VSWR of the antenna connected to the combiner does not exceed 1.5:1.
