G5rv Jr Attic

The infamous attic dipole.

G5rv jr attic.

Designed as 3 2 wavelength antennas for 14 mhz they provide reasonable performance on many other bands. In the same way that the both sides of the feeder can be strapped together and the whole normal size g5rv antenna used with a good atu to provide coverage of 160 metres top band so too the same technique can be used with the half sized g5rv antenna to provide 80 metre coverage. The history and basic theory of this antenna dates back to 1946. I wanted an invisible antenna so i m starting with an attic mounted g5rv antenna.

My worry is how can i satisfy my own and my xyl wife s concerns about rf in our house especially in the bedrooms immediately below the attic. This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up. Quasi inverted v 145 degrees at 24 feet a feed line of 80 ft and the matching segment hanging freely only 40m 20m 17m and 10m are usable 17m with swr of 7 6 requires an external tuner. Half size ham radio antenna.

Then we heard a long testimonial about how he d set one up in his parents attic and worked a ton of dx how he still uses them to this day and how they re the perfect antenna for working all bands. You can see it s clear of metal objects and the ladder line goes off to the right at a 90 degree angle. I assume that anyone who has a g5rv or g5rv junior in their attic has done so with ceramic spacers and has zigzag or dog leg installations or otherwise has contorted the antenna to fit up there. Mfj 1778m g5rv junior wire antenna multi band center fed dipole antennas.

Mac af4ps fp 51 note. The junior version from mfj that covers 40 meters through 10 meters on the ham bands. Swr of 15m is 22 12m is 25 and 6m is also 25. 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.

Half size g5rv or g5rv junior for 40 10 metres. Not ideal but i m avoiding. These are multi band center fed dipole antenna capable of 1 500 watts. With the peak of my g5rv jr.

Some were not amused others shook their heads and a few actually agreed with him. Antenna mounted as high as practical. The better your antenna the more success you will have making contacts.
