biquad best for homebrew?

Postby TheSovereign » Thu Jan 02, 2003 1:23 am

i just found a place that shows u how to build a standard biquad

started building and came out with cruddy looking first draft and was amazed at how good directional antennas are for distance(this being the first time i have ever used one)

well i was playing with it looking at it and i notice my measurements from the copper to the base was off so i measured and it was a whole 9 mm off and it was still picking up
i fixed it and now i get better snr but im truly amazed @ how crappily u can build these things and still come out with something usable

I was just looking at the biquad / primestar dish setup:

Would it be possible to create a more portable / covert version on the biquad primestar dish? Could you put a biquad in a cantenna?

I have a big cookie can. I think it is like 10" in diameter, none of those ridges. :-)

do you have to have a dish to use the biquad or is that a dumb question

1. putting a biquad in a can is useless, you are mixing two types of antennae
2. you don't need a dish to use a biquad
3. most of your questions can be answered by reading the FAQ threads and using search, e.g.
