G5rv Antenna In Attic

I wanted an invisible antenna so i m starting with an attic mounted g5rv antenna.

G5rv antenna in attic. 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. Calculating the actual fields is really hard. The antenna is in the attic probably only about 16 18 above the ground. Designed as 3 2 wavelength antennas for 14 mhz they provide reasonable performance on many other bands.

Power isn t actually radiated equally all over 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. I have build the recommended balun using 10 wraps of the coax feed and a 5inch diameter pvc pipe. They cover all bands from 40 10 meters with a wide range antenna tuner.

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. The junior version from mfj that covers 40 meters through 10 meters on the ham bands. There will be hot spots and cold spots. 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.

These are multi band center fed dipole antenna capable of 1 500 watts. Ground reflections and also any wiring in your house may reflect distort or focus the field making more hot spots. Not a good multi band antenna. At one point that g5rv was laying on top of a hedge row.

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. With the antenna in your attic you aren t even in the far field of the antenna. 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. G5rv best dang antenna i ve ever used he bragged.

Mfj 1778m g5rv junior wire antenna multi band center fed dipole antennas. 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. 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.
