Broadband VHF high band sidemount dipole, aluminium, 136-174 MHz, 250W, N-type female, 1m cable, 0 dBd - 785mm

Product code: B43

The B43 folded dipole antenna is designed for use as a VHF communications sidemount dipole, the B43 sidemount dipole antenna is manufactured for the VHF high band 136-174 MHz range. Stacking the B43 dipole antenna in an array formation will increase gain and give a more directional pattern. The broadband capability of the B43 suits multi-channel sharing through one external antenna, filtering of the transmitted signal utilising a band-pass filter or band-stop/band reject filter is recommended to ensure minimal to no interference between channels.
