The 2M5WL is designed with the SERIOUS “Weak Signal” enthusiast in mind. It provides excellent gain for minimum weight and windload yet is strong enough to survive 100+ mph winds. The modified folded dipole driven element is also unique as it’s center is a CNC machined block of aluminum fitted with 'O' ringed connectors and access cap. After factory assembly, the block is filled with a space age silicone gel which further seals and increases dielectric breakdown and arc-over protection. The 3/16” rod elements mount through the boom on UV stabilized button insulators. All hardware is stainless steel except forU-bolts. A vertical riser and an overhead Dacron cord guy system is supplied for boom support. This antenna is widely used in EME (W5UN’s 48 2M5WL’s and many others) and large Tropo scatter arrays.Several optional items are available to provide more gain from your 2M5WL’s. 2 and 4 port power dividers are available for matching stacks of 2 or 4 antennas. 50 Ohm phasing lines model VHF-50-2M5WL2 and VHF-50-2M5WL4 can be ordered for phasing 2 or 4 antennas together. ‘H’ frames, OR-2800 andMT-3000 AZ and EL rotators are also available as well as Rohn and US towers.

These antennas have fine gain and pattern performance but suffer from poor mechanical design. The tend to break at the first element hole in front of the boom to mast plate. The break perfectly bisects the hole so stresses are concentrating at that point. This has happened to me twice. I would not normally put up with this except for the excellent performance while the antennas are holding together. I am looking into how to strengthen the boom at the weak point. A shame I have to do your mechanical guys' job for you.
