A 4 element Delta Loop Antenna for the 11m band from our ‘Lightweight’ range.

During 2012 we had a few enquiries from both 10 and 11m operators who asked about producing a high gain lightweight Delta Loop for use mainly within a portable situation.

The main issue with producing big loops is the boom. Our older 30mm x 30mm x 2mm 6082-T6 boom stock was very strong but could not effectively support more than 3 elements at 10 or 11m. However, our hardware will also fit a 1.25 inch (31.75mm) by 10 gauge (3.2mm) square section boom and this is much stronger. We have since designed this antenna that uses this newer more robust stock. more so that all ‘Lighweight’ Vortex Antennas now use this as standard. You may notice that there is still a small amount of boom sag, so we’d advise choosing the antenna and fitting the optional boom sag reduction kit for permanent or longer term installations.

The antenna comes complete with a full mounting kit. The optional boom support kit includes 2 x M8 316 A4 Stainless Steel Eye Bolts which are located at the boom ends, premium Mastrant Synthetic Guying Line together with 316 A4 stainless steel turn-buckles help reduce the sag. The antenna is manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock and is an excellent balance between weight and strength giving the end user high gain in a small footprint. Antenna is supplied with all hardware including a boom to mast mount for a 50 mm (2 inch) pole.
