£710.00 — £750.00

Product Code – 10M4WWHEAVY

A 4 element Delta Loop for the 10m 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).

VORTEX BOOM TO MAST PLATES
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 a Buyer of this antenna in Holland:

“Dear Steve – My antenna has arrived today and you have congratulations for your construction. I have many antennas in 25 years of radio, but not yet in such a good quality as VORTEX – your company is a credit and build quality is MIL++++++ EXTREME!!. Unbelievable .. I am for sure glad I ordered from you because I do not think I would get anywhere as a good material. Thank you!. Vortex is a credit to ham community and your excellent antenna systems.
