A 5 band trap antenna
For this model the details as given by the ARRL Antenna Handbook, With a 75-Ohm twin-lead feeder the SWR with this antenna is under 2 to 1

Trap dipole antenna
My trap dipole exists in the form it does because, like many of us, the garden is too small
Traps-about antenna traps
It contains measurements of traps, performance of trap antennas using models of traps, and ideas on how to make trap antennas more efficient
Traps antenna 40/20 meter
More than 5 years ago I already made a few cheap traps and put a small piece about it on my website
Le mie sloper per 80/160 Lunghe solo MT. 17,50
Una trappola per gli 80mt con del filo di 2 mm avvolgendo 40 spire su un diam. di 50 mm e spaziate 3 mm interponendo un condensatore da 100Pf 10 kv

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
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
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
