VHF/UHF mast mount whip, dual-band, dipole/dipole, GPS, 3.0 m, 30-88 MHz, 225-512 MHz


Setting a new standard for elevated wideband communication, the VHF30512DB-DD-M combines two independent dipole antennas to offer a complete VHF/UHF solution.

Providing consistent communication performance across both the 30-88 MHz and 225-512 bands, the antenna is suitable for use on all elevated masts.  As the antenna does not rely on any monopole element it does not require a ground plane.

This single connector antenna can be supplied with an optional diplexer to split the VHF and UHF frequencies.

A mast mount base is supplied with a Ø40 mm socket ready to interface to a Ø39.5 mm spigot.
