ham radio yagi antenna
A question about yagi antennas (calling all hams)?
I know the basics of a yagi antenna and how it works….i also know that in a simple yagi, the driven element is a simple tuned dipole……i have a cb radio (dont worry i am a ham at heart) and i wanted to make a little more out of the four watts it has…..so i wanted to build a yagi for it (i was pretty bored) so i crucnhed the numbers and found out that because the frequency of the cb channels is fairly low, my yagi would have to be pretty big if i was going to build a half wave dipole as my driven element…….can i use increments such as 1/4, 1/8…etc. to build this dipole so i can downsize my antenna a bit, or would this just hurt my performance severley…..i know this would work on a normal vertical dipole, but would it work as a yagi element? (im visualizing using a 1/4 wave dipole as a driven element (two 1/8 wave wires) to make this work and downscale this antenna) also dont go into math too much….thats not my high point
If you google “CB beam antenna” you will see that there are many out there and none of them are compact. If there was an easy way to make a tiny cb beam antenna that was actually effective, someone would have already figured it out.
