During the years I have been building and testing a lot of wire antennas. One of the most interesting antenna is my MH-antenna which was described in the ARRL:s QST in March 2010. It is a small 3 element beam which works very well. This is a 18 MHz version:
This one is for 28 MHz:
Another interesting antenna is the Moxon antenna. This one is for 7 MHz:
The Flip Beam Antenna (FBA) is a variety of the Moxon antenna. You can change the direction of the antenna by a switch or relays at ground level. It has excellent F/B and gain is about 4-5 dBd. This one is for 7 MHz:
A vertical antenna called Spitfire for 7 MHz is shown here:
These dipoles for 21, 24 and 28 MHz is fed by the same coax cable:
This yagi for 28 MHz has a plastic boom and wires inside fishing rods for the elements:
Traps made of coax cable and wires supported by fishing rods makes a 2 element yagi for 21, 24 and 28 MHz:
This must be one of the smallest beams for 28 MHz. Elements are diamond loops:
This is a 2 element beam for 7 and 10 MHz. It uses traps and is designed almost as a Moxon antenna. The traps are designed by using VE6YP coaxtrap programme. The support line in the middle of the reflector is used to mechanical balance the antenna.
More antennas can be found at my website at: http://www.sm0dtk.se.
Good luck with your antennas! 73 de Martin
