A 1/4 Wave Vertical for 40 - 10 Meters
It consists of 3 sections of thick wall PVC connected together and may be self supporting

Antenna Vertical Links →
10 mt wire jpole
Radiator 14 or 18 gauge strander copper 16.5 feet
20 mt wire Jpole vertival end feed
Same as dipole advantage is omindirectional pattern and low angle radiation when hauled up high
20-Meter J Pole Vertical
The J pole vertical is built from a fifty-foot TV push up mast
40/15M band sloper
The tower guy wires could be used as additional antenna radiators. The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 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
