75 Meter Delta Loop Beam


It is vertically polarized, take off angle is less than 30 degrees.The half beam width is about 56 degrees.It changes directions by adding tuning stubs that can switch in and out.The antenna is tuned for 3.800 Mhz but also easy to modify

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

L'Antenne Delta Loop
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
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


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m

A simple SWR Meter is to be used at HF

A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
