Wallen Antennae - Sleeved Helical Antennas

The sleeved, hand portable helical antennae can be supplied factory tuned or in uncut lengths.  All uncut units are supplied with a cutting chart specifying the exact number of turns to remove to achieve a specific frequency.  This is more accurate than cutting to length and also allows installers more flexibility in their use of stock.

The sleeves are flexible and are made in a soft yet durable material which minimises the risk of injury from contact with face or body, which at the same time is able to resist the wear and tear typically encountered in civil engineering, maintenance and other such environments.
