Building a GP for 40, 80 and 160 meters

Antenna 80 meter Links

188



Sloper per 80/160 lunghe solo MT. 17,50
This type of antenna has been installed for more than a year with interesting contacts on both bands

80-160 antenna for the small garden
I decided to make a trapped 80-160 meter vertical dipole with the feed point at 11 meters

80-160 metri
This antenna is to be used in a small space available

Antenna for the Low Bands..80 and 160m
I'm now using 45ft dipoles. loaded top and bottom cap hat wires on 80 and 160m, suspended from a 60ft high timber mast


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

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
