Antennas
 

Was at a field day thing this past weekend. I wasn't there when they
set everything up. There were 3 antennas in use. One very clearly
was a Yagi. One of the others very clearly was a "vertical" and the
other one was like a wire running the length of the parking lot and
was up about as high as the building - then it had a middle wire
running in to the shack with the radio. I was told that was a
horizontal antenna. Isn't there more specific names for vertical and
horizontal antennas than just vertical and horizontal??

Thanks.

The terms vertical and horizontal refer to the polarization of the
electric field the antenna operates on not the type. A Yagi antenna can
be vertically or horizontally polarized for example.

Thanks - actually I was wondering if one of them might have been a
beverage antenna because it was really long - but then the feed point
was in the middle so I guess not. Thanks for the info - I appreciate
it.

I love beverage antenna's when you can get one out, but today's
overdeveloped areas make it hard to find a place. Much is written
about beverage antenna's, books and books in fact going into great
technicality. But here in South Africa we just throw out a bit of wire
and get great results.

My pal Gary in Cape Town just runs out 220m/700 ft of wire called a
BOG, beverage on the ground, just on his suburban road outside his
house, or at best he goes down to the local sportsfield and runs it
out there. He gets amazing results from this.

Of course the purists will tell you that the beverage has to be dead
straight, terminated into a resistor and supported about 1.2m/5ft off
the ground, but in years of playing with these antenna's we have got
great results with a not too perfect layout and no termination.

Give it a try and have fun - you will be well rewarded with some super
catches.

The termination at the far end only solves the problem of the antenna being bi-directional, that is of course
receiving signal from both the direction the wire is running (and, off the back end where it is fed).

Did have a place accessible to me at one time where we had 6 permanent Beverage antennas set up, all terminated. A
very nice place to DX, but always a lot of repair work on the wires as they ran through a wooded area.

We don't terminate here for two reasons:
1. the ground here is too dry and you can't get a proper earth
2. We actually like the open end in both directions as one end you get
Aussie and the other end N. America. Like a double whammy.

So you can DX Aussie at sunset/evening and N. America mornings/
sunrise. Makes the DXpeditions quite worthwhile.

Wow! a six beverage site = sheer DX heaven!

Ya, that's a problem with long beverages - people and animals walking
all over them and pulling them down. Another problem here is the high
price of copper will see your wire stolen from right under your nose
while you are busy DXing these days in mwaAfrika.
