I built many yagis in my youth, and as long as the main dimensions

Thanks everyone! Now I know.


Something no-one mentioned here was the lack of a balun which could
wreak havoc with weak digital signals due to standing waves on the
cable. The most popular home-made types these days seem to be the
bow-tie + reflector + balun design.

Does the lack of a balun actually cause standing waves on the cable?


No but it helps eliminate them )
