G5rv Antenna In Attic

Not a good multi band antenna.

G5rv antenna in attic.

There will be hot spots and cold spots. 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. Ground reflections and also any wiring in your house may reflect distort or focus the field making more hot spots. G5rv need to be mounted high enough that the ladder line is vertical for best operation.

The g5rv multiband wire hf antenna provides a very convenient cost effective multiband antenna solution for hf ham radio communiations and as a result it has been popular for many years. At one point that g5rv was laying on top of a hedge row. I have build the recommended balun using 10 wraps of the coax feed and a 5inch diameter pvc pipe. Furthermore in this particular application an attic where the antenna will have to be bent around corners the g5rv offers no benefits over other options available even on 20m.

Power isn t actually radiated equally all over the antenna. Mfj 1778m g5rv junior wire antenna multi band center fed dipole antennas. The antenna is in the attic probably only about 16 18 above the ground. The junior version from mfj that covers 40 meters through 10 meters on the ham bands.

It s laid out pretty much as good as i can but the 450ohm ladder line is most certainly more horizontal than perpendicularly and vertical to the antenna. You can see it s clear of metal objects and the ladder line goes off to the right at a 90 degree angle. G5rv best dang antenna i ve ever used he bragged. These are multi band center fed dipole antenna capable of 1 500 watts.

If you want to give that up as modest losses to use a g5rv when other options are available that perform better and don t incur such losses go for it. The vhf enhancer rods cover channels in the 2 13 range so that you have fewer blind spots and the smartpass amp helps the antenna deliver the correct balance of short and long range reception even when located in the attic. Designed as 3 2 wavelength antennas for 14 mhz they provide reasonable performance on many other bands. Calculating the actual fields is really hard.

Here s a guy that operates with a 102 g5rv at 18 and a half wave vertical dipole in a side yard tree about 20 at the top of the antenna covering 10m. I wanted an invisible antenna so i m starting with an attic mounted g5rv antenna. The g5rv antenna is based upon the doublet antenna concept and it was designed by louis varney who held the amateur radio callsign g5rv.
