£430.00 — £465.00
Product Code – 20M2WWHEAVY
A 2 element Delta Loop for the 20m band from our ‘Heavy Duty’ range. The antenna is manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom which is guaranteed to give you many years of excellent service.
When conditions begin to fade on the higher bands, here is your opportunity to get onto ’20’ and still enjoy the DX with a great compact full size 20m beam antenna.
A common advantage with a Delta Loop is the very compact footprint as the antenna has very little width (Good news when you don’t want your metal overhanging your neighbours’ garden!)
The Delta Loop is similar electrically to the ‘QUAD’ and the well known analogy of ‘First In and Last Out’ on the band rings very true with all Delta Loops.
Having spoken to some well know antenna gurus we think it’s because although the polarity is ‘Horizontal’, the physical orientation of the loop means there is a certain amount of ‘Vertical Polarisation’ – this will help to reduce fading, especially when working ‘DX’.
The Vortex 20m Delta Loops have 5 sections of vertical tubing as standard. The antenna includes 6.35mm Diameter Wide Plate Element Brackets and Heavy Duty Polyamide Element Clamps manufactured by premium supplier ‘Stauff’ in Germany.
Our Delta Loops for the 17m band (and lower bands) have an additional stainless steel horizontal support bar which acts as a support brace, reducing the flexing of the vertical arms of the loop sides as continued flexing would cause metal fatigue and the arms could subsequently break. Check one of the images left for a more detailed look at the brace and the components.
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.
