Can you use a pipe cutter or a hack saw, can you solder – then here is how to build a SIMPLE ”J” antenna that will more than double your 2 meter (and even 440) performance! by Dale “Kuby” Kubichek, N6JSX
Do you have trouble getting your mobile signal into the LEO satellites? Try this small 2 meter vertical antenna with your mobile rig or HT and enjoy more success in your uplink. I built this small vertical because I could not uplink very well at low elevations and I just could not bring myself to
The W5UN Quagi 97 is a computer optimized quagi derived from the original W5UN Quagi of the early 1980s. The length of the 1997 model has been deliberately shortened to allow it fit on a 24 foot boom. Performance is substantially higher than that of the original antenna. It now compares favorably with yagis of
This antenna does not need a 75 Ohm transformer as quads do at lower frequencies. Any length of a good quality RG58X will suffice as the primary feedline. Connect to station with any length of good 50 ohm coax and PL-259 connectors and one barrel connector to couple the feed lines. This antenna can be
This article taken from QST September 1994 is about a vertical dual-band antenna for 144 and 430 MHz made with a TV twin lead and coax cable.
Editors notes: The antennas described in this article were built as the result of several discussions between Kent and a Cuban radio operator. While there are plenty of high performance antenna designs, most of the parts required to build them are not available in Cuba. There just isn’t an EPO or Radio Shack available in Cuba.
Attic antennas can work better than you might think, some of mine work as well as their outside counterparts
One of the easiest and quickest antennas to build is the Vertical Bazooka, which is made entirely from coaxial cable.
