UHF 3 element square boom Dual polarised Yagi, aluminium, 380-520MHz, specify 20MHz, 150W, 6dBd – 700mm

UHF 3 element square boom dual polarised Yagi, aluminium, 380-520 MHz, specify 20 MHz, 150W per input, dual N-type female, 6 dBd - 700mm

Product code: Y403-DP

The Y403-DP 3 element dual polarised UHF Yagi antenna allows for 2 x input Tx frequencies or 2 x Rx frequencies with 90deg isolation between signals for minimal interference, all in one antenna, reducing space requirements on your tower, structure or mount pole. The Y403-DP can be mounting in the conventional H&V polarisation utilising a standard A48 or for +/-45deg using a A48-AM. The 2 inputs can be phased together with either a coaxial phasing harness or power divider to create an X-pol or specify circular polarisation requirements.
