Of all the G5RV antenna system cousins the ZS6BKW antenna system has come closest to achieving the goal that is part of the G5RV mythology.

G5rv antenna plans. A multi-band HF antenna consisting of a single wire and simple matching system to cover as many of the amateur HF bands as possible. Depending on which bands you want to operate there is a better design which involves shortening the antenna and lengthening the section of ladder lineG0GSF ex-ZS6BKW came up with a similar design that is a significant improvement over the G5RV. KK5BL How To Build A G5RV Antenna How to build a G5RV Transmitting antenna Originally posted to the packet bbs system by KC6CFF.

Variations of this antenna have seen it cut in half to two horizontal elements totalling 51 feet G5RV Junior and mounting it as an inverted vee antenna. G5RV Antenna Design G5RV is a dipole that is 3l2 long at 1415MHz fed by a l2 balanced line matching section approx. The G5RV Antenna System Re-Visited The G5RV Antenna System Re-Visited Part 1.

Wires 1 2 represent the antenna wires 3 4 the vertical ladderline section and wire 6 the coax section. Louis Varney G5RV invented this antenna in 1946. Actually its a design from ZS6BKW aka G0GSF similar to the G5RV but it actually resonates on five bands well 6 actually and doesnt rely on a tuner ATU to make it work.

The interaction between the radiating section and the feed-stub makes the G5RV usually easy to match on all-bands from 80 through 10 meters with an ordinary low-cost antenna tuner. The design appeared in TT RadCom Jan Feb 1993 but is also in Pat Hawkers Antenna Topics publ. Although the G5RV antenna with 31 feet 1036 metres of open wire before transitioning to twin or coax is a convenient option another solution is to use an antenna tuning unit.

The G5RV is an easy-to-build 80-10 dipole requiring no traps. This project gives instruction on how to build my version of the G5RV wire antenna that is used on the 10-40 Meter Ham Radio bands 28MHZ to 7MHZ. It was invented by Louis Varney.

The G5RV is an excellent choice for the 20 meter band. RSGB 2002 Its only 90 ft long 2751 metres with a 40 ft 122 m downlead. Jones Antenna Handbook -- 1937.

The basic G5RV antenna measures only 102 feet across the top for 80 thru 10 meter operation and is fed at the center through a low loss 34 feet feed-stub. Half Size Ham Radio Antenna. Here is the ZS6BKW antenna installed at AK6R fine tuned for the CWFT8 frequencies on 40-20-17-12-10 meters.

An excellent antenna when installed at 30. Using copper tubing open line for matching Appeared in the December 1935 Collins Signal Also in The Radio Antenna Handbook -- 1936 Also in The Frank C. A multi-band HF antenna consisting of a single wire and simple matching system.

The purple lines show the current distribution along the wires. The history and basic theory of this antenna dates back to 1946. The G5RV on 20 meters L.

Of all the G5RV antenna system cousins the ZS6BKW antenna system has come closest to achieving the goal that is part of the G5RV mythology. The ZS6BKW Multi-band HF Antenna April 7 2017 This is the antenna for you guys who want to get on HF effectively and havent too much space or cash to throw around. The G5RV has high SWR by design on most bands and a tuner is required.

All bands are covered including 30 17 and 12. All bands are covered including 30 17 and 12. Basic G5RV antenna with 31 feet of twin transitioning to 75 O twin or coax.

The Half-Wave Dipole Antenna The G5RV tends to resonate around 14 MHz which is pretty well mid-way in the HF spectrum and makes it a good general antenna. Unlike most dipoles the basic design is not a 12 wave but instead a 32 wave dipole on 20 meters. According to an acknowledged expert in computer antenna design and modeling L.

If youre a fan of the classic G5RV antenna designed by the late Louis Varney G5RV you may find this video from the Stamford Amateur Radio Association W1EE most fascinating. The team in this video discusses how to design build and use an improved variant of Varneys original antenna known as the ZS6BKW. According to an acknowledged expert in computer antenna design and modeling L.

The antenna can be erected as horizontal dipole as sloper or an inverted-V antenna. The ZS6BKW antenna is a better match for our bands than the G5RV. Later adjustments took account of the different type of balanced feeders that could be used.

Actually its a design from ZS6BKW aka G0GSF similar to the G5RV but it actually resonates on five bands well 6 actually and doesnt rely on a tuner ATU to make it. 520 O Zo and an arbitrary length of coax or low Zo balanced line to a tuner. It is an antenna system including a radiating element and a length of transmission line designed to present a correct impedance at a design frequency.

The G5RV has high SWR by design on most bands and a tuner is required Homebrew G5RV. The G5RV antenna is a dipole with a symmetric resonant feeder line which serves as impedance matcher for a 50 ohm coax cable to the transceiver. Collins Multi-band Antenna 1935 Collins Radio had a very similar antenna Multi-band 2 3 or 4 band depending on config.

The method of construction and tuning is essentially the same for both antennas but the dimensions are different. 7 House Tree or other end support. The diagram above shows what can happen if you dont include the balun.

It is very popular in the United States. Although Varney envisioned his design primarily as a 32 wavelength antenna for the 20 meter Amateur Radio band radio amateurs have used the antenna for multiband use. The G5RV is an easy-to-build 80-10 dipole requiring no traps.
