40 Meter Parasitic Delta Loop Array


40 Meter Parasitic Delta Loop Array

On 40 meters, my experience is that you need at least 20 dB of F/B ratio in order to be able to turn down European broadcasters enough to be able to hear the west coast stations, especially the west coast stations with dipoles and 100 watts

Antenna Delta Loop Links

Inverted Dipole Delta Loop, DK5VQ
For relays 160m 1 and 4 are energized, the antenna works as a folded dipole

L'Antenne Delta Loop, ON5CFT
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
