£395.00 — £430.00

Product Code – 11M3WWHEAVY

A 3 element high gain Delta Loop for the 11m band from our ‘Heavy Duty’ range. Manufactured from lightweight but extremely strong construction grade 6082-T6 stock with a h/duty dual section boom.

In the center boom section we use a 60mm x 60mm x 4mm wall section of 6082-T6 stock which forms the main support piece. On the ends, a 50 x 50mm x 10SWG (3.2mm wall) square box is used to support the reflector and the director element.

As standard the antenna includes 6.35mm Diameter Wide Plate Element Brackets and H/Duty Polyamide Element Clamps, complete with M10 Stainless Hardware. Antenna is supplied with all hardware except boom to mast mount (see below). Normally hi-gain antennas have a limited bandwidth, however modelling for this antenna has produced a design with approx 1MHz 2 to 1 SWR bandwidth figures.

The top wires on each loop are manufactured from copper-clad steel (in essence copper coated stainless steel) which is extremely strong and robust. The breaking strain of this alone is over 250kgs. This wire is the secured using marine-grade (316 stainless) hardware and Vortex’s unique “Cable Strain Relief Mechanism” which pretty well eliminates a top-wire failure.
