The delta loop
A vertical-plane equilateral delta for 40 metres will be about 48ft 5in wide and 42ft high. This places limits on the height above ground of the lowest point, since with a 35ft low-point height, the high point is 77ft up

Auto Tune Multi Band Delta Loop Antenna
The tuner cannot be tuned to an antenna of any size. The power to the part where the voltage is off has a high impedance and the change tends to be steep, making it difficult to tune
Corned Fed Delta Loop
The Delta Loop antenna is one of the famous magical antennas, but in reality, the Delta Loop antenna is not as magical as it's reputation. Despite its reputation as a Multi band antenna, it is a single band antenna. It can be somewhat tricky to make a Delta Loop
De Delta-Loop
A delta loop is a closed loop antenna that normally forms an isosceles triangle. If the delta loop is constructed as an isosceles triangle, it has a gain of approximately 0.5 dB relative to a dipole. The impedance will be around 70 ohms. If we flatten the triangle a little, the impedance can quickly rise to 100 ohms and more. The total length of the conductor can be calculated as follows: 306.3 / f f = frequency in MHz

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 An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
