£750.00 — £795.00

Product Code – 11M4WWHEAVY

A 4 element Delta Loop for the 11m band from our ‘Heavy Duty’ range. Manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom. This antenna includes 6.35mm wide section plate element brackets to compliment 3 sections of aluminium tubes used in the vertical sections of the elements. Heavy Duty Polyamide Element Clamps, complete with M10 Stainless Hardware are supplied as standard. Large antennas such as this model also come complete with an additional support strut. This support is used to reduce boom sag and anchors the boom in two (2) locations, one at the front and one at the rear. For our guying line we use ‘Mastrant’ 4mm synthetic guy line which is rated at 400kgs. To compliment the setup, 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. Download our TOP-WIRE info sheet. The antenna is supplied with all hardware except boom to mast mount (see below).

All VORTEX Antennas can be shipped WITHOUT any boom to mast mounting plates. Select this option from the drop-down menu when purchasing. Other options include the choice of mounting plates and complete mounting solutions with U-Bolts and Brackets.

From one of our buyers:
Hi Steve,
Just an update about the antenna – I’m VERY VERY impressed with it.
It’s working absolutely fantastic and I’m having some great signal reports from it. Also getting great rx signals too – thanks very much. Blows my old Moonraker 4 away totally. No doubt, all the top DX stations now all run VORTEX. It is THE system to have – the others don’t come close, both in build quality or performance. 73’s and keep up the great work and designs.
