Ihad used cubical quads for many years and the decision for 20 meters and up was easy, but what to do For 40 Meters? Some years ago I built a MOXON Rectangle antenna for 6 meters. The performance was excellent with good gain, great side and back rejection and seemed to work very well. Cost to build was very low and Construction was very easy.
TheVertical Buddi Beam for 20m - The Vertical Buddi Beam on 20m using no Coils. n this article I am going to describe a totally new way to construct and use a very old design the two element Yagi antenna. Unlike the traditional Yagi this design does not require a Tower or a boom, it is 100 percent portable and most important high- performance and easy to assemble using standard Buddipole
2mantenna dimensions: Oblong 360 mm wide x 690 mm high, 1/6th of a wavelength wide and 1/3rd of a wavelength tall. The oblong ratio is 1/3rd across and 2/3rds high. My finished antenna wire length is 2.130 metres, which includes an extra 15 mm on each side for feed point strain relief. The finished length will depend on the wire diameter used.
Weare going to feed our Yagi with coax and minimize the losses and likelihood of common mode currents on our feed line at the same time. The Dipole Centre. The dipole is an important part of the Yagi, anything that goes on (or wrong) here is reflected throughout the rest of the Yagi. Below are 2 images of a Dipole removed from a Yagi.
. #1. Last week I ordered the Arrow II 146/437-10WBP handheld 2 meter/440 Mhz yagi antenna directly from Arrow Antennas. I also ordered the roll up storage bag with the pockets that is made in the U.S.A. The price for the antenna is $139 and the bag is $40. This antenna is specifically designed to allow you to work the satellites
2El Portable Yagi for 10-20 mt - This Yagi has a constant element-distance of 1,50 m. You must only correct the lengths of the elements for QSY, see table down. For the bands 10 m and 12 m the Yagi is working as a reflector-radiator-Yagi, for 15 m and 17 m as a beam with radiator and director.
6meter, 2 element yagi. A simple, compact and effective antenna for 50 Mhz. This antenna was built in about an hour after using K6STI's AO simulation software to design it. To build it you will need: 1/2" or 5/8" OD aluminum tubing - 2 pieces: 109" and 121" long; 7/16" or 1/2" OD solid insulating rod - nylon, plastic, or wood - 6" long
