Product Code – 12M5WWHEAVY

A 5 element Delta Loop for the 12m band from our ‘Heavy Duty’ range. Manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom. As standard the antenna includes 6.35mm Diameter Wide Plate Element Brackets and H/Duty Polyamide Element Clamps, complete with M10 Stainless Hardware. Large antennas such as this model also come complete with an additional ‘T-Bar’ horizontal strut/support. This support is used to reduce boom sag and anchors the boom in four (4) locations, 2 at the front and 2 at the rear. By using four support points (rather than two) – also reduces the sideways movement of the boom. For our guying line we use ‘Mastrant’  4mm synthetic guy line which is rated at 400 kgs. To compliment the set-up, S3i 316 Marine Grade Stainless Steel Eyebolts, Turnbuckles and Hardware finish the project. The antenna is supplied with all hardware except boom to mast mount (see below).

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.
