They're (sadly) out of production now but sometimes you can find used ones In the January 2019 issue of QST, I introduced the slot-cube, a remark-ably small 2-meter base station antenna, with similar gain to a J-pole, and, like the popular homebrew ver-sion, soldered together from 1⁄2-inch copper water pipe. Features/Specification Type: Aluminium Vertical with Unun matched base Frequency TX: 80 to 6M (3. Resources listed under J Pole category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators. Antennas/10M; Antennas/Vertical; The title of the main category is Vertical and it deals mainly with Vertical Antennas Projects. It’s a good straight forward design and looks to have a natural impedance of around 40-50 ohms as no matching device is included which sounds ok, but lower impedance Yagis of around 30-35 ohms offer better performance and are He called out to me on 50. 145 Mc 5/8-wave vertical antenna by ON6MU At VHF, both the 1/4-wavelength monopole and the 5/8-wavelength monopole antennas are widely used. I used the standard formula for a dipole (468 / Freq mhz = total feet. This vertical antenna is made from coaxial cable. 20m Boom So, this month’s [March 2021] antenna project by Mike Parkin G0JMI is a ‘homebrew’ build of a 3 element 6m Yagi. We tuned the antenna using an MFJ-948 antenna tuner which brought the antenna closer to 50 ohm. 12m - Homebrew 2-element yagi at about 37' on the short tower. I also didn’t want to build an antenna that required special matching devices. 2 db gain over the dipole antenna and 1/2 vertical. 1 Meter(13. The antenna itself is an off-center fed vertical dipole made by flipping an electrical quarter wavelength of braid back over the outside of the coax. 95 The length of radials for a 20 meter amateur radio band should ideally be a quarter of the wavelength, which is approximately 5 meters at a frequency of around 14 MHz. Works fine for me. This sim-ple yet powerful design for a copper J-pole can remove that disability. I also use an EARCHI end feed random wire on 40-6m, typically as a Now to compare it to the vertical I'm already using. I have been operating from an apartment in Maracaibo, Venezuela for over a year and during that time have worked well over 100 countries, all 50 states on At Chilicon 2011 some of the members of the Ottawa QRP Society arrived with a homebrew vertical antenna. 1 female PL 259 6m 1/2 wave Melrose Vertical Posted on June 5, 2024 Posted in HF Antennas.
