Low Profile Aerials
Hi-Tec’s low profile antennas are special application antennas for installations where minimum overhead clearance is available and where vibration may be severe. They are used in industries such as the railway and forestry.

Hi-Tec's low profile antennas are special application antennas for installations where minimum overhead clearance is available and where vibration may be severe. They are used in industries such as the railway and forestry.
The LP-VHF model is fabricated from series 6000 grade aluminium which is then welded. Completed antennas are finished with an epoxy coating to provide a weather resistant finish.
The LP-HD-FMRX model is a heavy duty design manufactured from cast aluminium and suitable for heavy industry use such as railways. Completed antennas are finished with an epoxy coating to provide a weather resistant finish. This model is supplied factory tuned.
The radiation pattern of all models is equivalent to a 1/4w antenna, vertically polarised when mounted on a horizontal ground plane and is essentially omnidirectional.
