Three Easy DIY Antennas for Beginners

[abcd567]

@G8JNJ

I 100% agree with abcd567 comments.

Don’t run until you can walk

Build a dipole or 1/4 wave ground plane antenna first, then you have a reference to test other more complicated designs against.

In many cases problems associated with slight differences in material, dimensions and construction techniques, reduce the effectiveness of such designs. These frequently turn out to be less efficient than easier to build, and more tolerant designs such as the 1/4 wave ground plane.

The Coax Collinear shown earlier in this thread is a good example of a design that frequently appears in different guises on the internet, but is not likely to work at all well.

If you put a lot of effort into building a complex antenna, surely it’s worthwhile taking an extra bit of time to test it against a known reference, in order check that it is performing as it should do ?

Sadly very few people seem to do this before posting on the internet, so flawed information continues to propagate.
