Inverted Dipole Delta Loop, DK5VQ

For relays 160m 1 and 4 are energized, the antenna works as a folded dipole

To calculate a Delta - Loop antenna the formula is relatively simple: we take the formula 1005 / F, here if we want the Delta Loop to be qrv any Band it must be calculated on the lowest frequency, we take as an example the 3,500 Khz

Antenne delta-loop 160, le 80, le 40 et le 30m, F6CDX

My delta measures 166m perimeter, has the shape of an isosceles triangle 2 identical sides are horizontal and is located at 18m from the ground, I use this antenna delta loop for my HF connections, and in particular for the 160s, 80s, 40 and 30 m

Mini Delta, G3EJS

The author had been searching for acompact beam which could beeasily and quickly assembled forportable operations from Scottishislands, because time wastedassembling a complex station on anisland means that many lose thechance of a QSO with that island
