Product Code – 30M1_20M2_15M2_10M2TORHEAVY

A 1/2/2/2 element quad-band interlaced Yagi Antenna for the 10, 15, 20m and 30m bands from our Tornado ‘Heavy Duty’ range.
Manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom. The antenna includes Heavy Duty Element Brackets, Heavy Duty Polyamide Element Clamps and comes complete with M10 Stainless Steel Hardware. All elements on 10, 15 and 20m are full size with no traps or loading.

To retain efficiency on 30m, a linear loaded element is used. Linear loading enables the antenna to be shorter than a full-sized model (in this case approx 75% of full size), but retains a performance fairly close to the full size model. An equivalent antenna with traps would be far less efficient. Normally for the 30m band, the full dipole length would be around 14.8m. The Vortex design has leg lengths of only 5.5m each side (Just over 18 feet) so is ideal where space is limited or restricted. Compared to a dipole, the single 30m element has slight gain and directivity at approx 3.08dbi. 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.
