Inverted Vee as a multiband antenna
Here is a photograph of my inverted Vee antenna. In this picture the wires of the antenna and the guy wires of the mast are clearly visible. I took this picture early on a winter Saturday morning, when the wires were covered by half an inch of ice. (Hi) 15 Minutes later the sun had melted the ice. The blue wire of the antenna is most of the time invisible for the eye against a blue sky. So the antenna never before showed up in a picture.
The wire on this side of the house is 10.7 meters long and supported about 2.5 meters above the ground, and is sloping to the east. The other wire is sloping to the west and supported by the rain gutter on the other side of the house. This wire also has a length of 10.7 meters, and is folded back over a length of about 4 meters. The antenna is symmetrical and is fed via a 300 ohm ribbon.
The inverted Vee is used as a multiband antenna for all bands from 1.8 MHz to 144 MHz. In the shack on the first floor I use a homebrew symmetrical tuner for 80m to 10m. The antenna needs to be tuned on every band. I have to tune the antenna every time when I change bands.
On 80m the antenna needs to be retuned every 20 kHz. And on 160 m every 5 kHz. On 160 m an extension coil is used with the tuner. Because my symmetrical tuner is disigned for frequecies under 30 MHz, I use my holiday transmatch on 6m and 2m . This asymmetrical tuner, also works great with the symmetrical antenna.
On 40 m to 10 m I often use the lowest possible power. When the propagation is very good to extremely good my power can vary from 500 mW to 5 milliwatt. On 160 m and 80 m usually a power of 5 Watts is needed.
Even when my Inverted Vee had one leg missing, years ago, I still made QRPp and QRPpp QSO’s for about one year. hi.
