Product Code – 10M3-15M2-20M2WWHEAVY

A 3/2/2 element Tri-Band Delta Loop for the 10, 15 and 20m band from our ‘Heavy Duty’ range. Manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom. This tri-band antenna features 5 sections of 6082-T6 or *AA6082-T6 tubing on the 20m vertical sections, 4 on the 15m and 3 on the 10m.

The antenna includes 6.35mm Diameter Wide Multiplate Element Brackets and H/Duty Polyamide Element Clamps and comes complete with M10 Stainless Hardware. 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).

Following the initial modelling, we found that using 2 elements on 10 meters gave poor results and a front to back of only around 10db. This model has a slightly longer boom and has an added third element on 10m to restore the gain and front to back ratio.

The antenna has 2 full size loops on 20m, 2 on 15m and 3 on 10 meters giving you mono-band performance on each band.

New owner Ernest (OE3IDE) says this about his new antenna. Hi Steve, the antenna works perfect!! Every second station asking “You’re booming, which antenna do you use?” :-))))) Worked States, Canada, Dom.Rep, Azores, Egypt, …. mostly 10-20 over 9 :-))
