Following on from our very successful 5 element ‘Competition Class’  Delta Loops and the mighty 6 element ‘ F5 Tornado Loops’, Vortex now have expanded our super heavy duty 10 and 11m Delta Loops to include 7 elements within the range. ‘The Black-Hole’  is a formidable antenna and an extreme performer – built for operators wanting something just a little special! With a boom length of  14.75m, you’ll work stations that others won’t even hear and create your own propagation. You’ll devour stations with ease from the extremities of the globe. The 7 element is manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a super heavy duty boom. The antenna includes 6.35mm wide section plate element brackets to compliment 4 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. Many of the hardware items also included are bespoke to this design. We include additional horizontal element supports using 8mm stainless bars for extreme weather environments. All this combined gives you a massive 12.83dbi forward gain and a front to back of over 27db at the design frequency of 27.555MHz.

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 eight (8) locations, 4 at the front and 2 at the rear and 2 in the center. By using multiple support points – also reduces the sideways movement of the boom. For our guying line we use ‘Mastrant’ 4mm synthetic guy line which is rated at 400kgs. 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).

This antenna is only available as ‘Super HD” because of the boom length. Our booms includes a 4″ (101.6mm) x 1/4″ (6.35mm) wall center boom section and 2 mid sections of 3.5″ (76.2mm) x 1/4″ (6.35mm) wall. The outer sections are 2.5 inch units but with a very heavy wall thickness ( 3/16ths) 4.76mm.

Because of the antenna’s weight, please contact us for a bespoke price on shipping to your country as this is not included in the quoted price
UK buyers can take advantage that we will deliver full boom sections (rather than cutting) – an advantage when buying on home turf!
