Rotary dipole 12 and 17 meters
To complete the trap have a look at any text concerning wire antennas and then mount the traps, so made, at the ends of the dipole already tuned on 24 Mhz

The L7 HamLoop antenna for 17 meters
an antenna for 17 meters using 18.1375 as the center frequency. By changing the frequency and wire size, the software calculates the measurements

The Lowly Quad for 17 meters
it is far better that the two element wire beam . I don't need the linear into Europe very much depending on propagation, my reverse beacon reports are great

The Dualband-Moxon-Beam for 17 m and 20 m
The antenna is fed with 50 Ohm coax in the middle part of the 17 m radiator wire 10. The 20 m radiator wire 2 is connected with a transmission line. This transmission line is made of 75 Ohm foam coax V=0,82

Dipolo rottativo 17-12-6-modulare
Questo dipolo rotativo, nella versione base, realizza di fatto piu' antenne in una, lo abbiamo definito modulare in quanto e' facilmente espandibile con degli appositi kit


Take off angle of horizontal antenna

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

Build a Three-Way Antenna Switch and Display

Build a Three-Way Antenna Switch and Displa To use a wireless relay to select one of two high current capacity power relays

5 element yagi antenna for 28.5 Mhz

5 element yagi antenna for 28.5 Mhz Gamma match will be made with a 1/2 "aluminum tube and a 75 cm coaxial piece of RG8 without sock and sheath inside the tube
