Overview

What it is and who it is for

The EhubAmerica TXAB144430 is a dual band omnidirectional base antenna for 144-148 MHz (2 m) and 430-440 MHz (70 cm), with 6 dBd gain on VHF and 8 dBd on UHF. It uses a 5/8 wave design with 2 elements on VHF and 4 elements on UHF, vertical polarization and 50 ohm impedance, rated for 200 watts.

Construction is fiberglass tubing with a hermetically sealed radiator and coil, 2.54 m (8 ft 4 in) tall with 52 cm radials. It fits masts 30 to 62 mm in diameter, is DC grounded, terminates in an SO-239 (UHF female) connector, and is rated for 110 mph winds.

  • Best for: amateur radio base stations operating on the 2 m and 70 cm bands.
  • Fits: SO-239 (UHF female) termination; masts 30 to 62 mm (1-3/16 to 2-7/16 in).
  • Important to know: its bands are the 144-148 MHz and 430-440 MHz amateur allocations, not the commercial land mobile bands. Coaxial cable is not listed as included.
