Jednoducha antena pro pasmo 1296 MHz
The SHF 1296 and 2304 MHz bands are also waking up in our country
Low-Cost Horn Antennas for 23-cm EME
23 cm EME stations have excess gain and power levels to communicate with low power stations

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
