Product Description

Product Description

6~30dB Directional Coupler(136-174MHz/350-520MHz, N Female, IP65)


VHF and UHF Directional Couplers are used in a variety of RF combining, sampling and power splitting applications, typically used in DAS (Distributed Antenna Systems) for sampling RF for fibre fed systems and distributing power throughout feeder cable networks. Using directional couplers suitable for covering UHF to high end cellular frequencies saves on the cost of upgrades when public safety radio coverage may have to be accommodated on a DAS designed for cellular coverage.


Topwave Telecom VHF and UHF series directional coupler with corresponding frequency range 136-174MHz and 350-520MHz. Such frequencies are very low and narrow, while they are necessary to a public safety radio system and cellular DAS network.
