A Tri-band Delta Loop Antenna aimed at operators interested in the higher bands. Following our review in RADCOM (December 2011) which pitched an ARRL Design 5 element Yagi against a Vortex 4 element Delta Loop (of the same boom length), you can see with accurate computer modelling using proven NEC based code, it’s obvious that the amount of elements is NOT the key issue.

In solid tests, the Delta Loop with one element less than the Yagi (on an equal boom length) out performed the Yagi by a reasonable margin, especially on the longer distance contacts. Data confirmed the Delta Loop radiation angle was 3 degrees lower than the Yagi (On an operating height of 15m) – thus giving it a significant advantage on the longer distance DX contacts. Based on this, Vortex have developed a tri-band Delta Loop for higher band enthusiasts with 2 active elements on 10m, 2 active elements on 6m and 4 elements on 4m. On 6m the array picks up added gain of more than 1.3 dbi over a normal 2 element array with the 10m elements adding more forward gain. This array proves to be a very solid performer, especially on 4m. The old analogy of the Loop/Quad being ‘First In’ and ‘Last Out’ on the band stands the test and is frequently proven to be correct. Antenna is supplied with all hardware except boom to mast mount (see below).
