Low Profile Aerials
Designed for installations with limited overhead clearance, our low profile antennas deliver reliable VHF/FM performance in demanding environments where vibration and durability matter. Ideal for railway, forestry, and heavy industry applications, these antennas are built from robust aluminium construction and finished with a weather-resistant epoxy coating.
With an omnidirectional radiation pattern equivalent to a 1/4 wave antenna when mounted on a horizontal ground plane, they provide dependable, vertically polarised coverage in harsh operating conditions.
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.
