Hello all readers, this is the Swede again.
This time I have been playing with a piece of pvc pipe and some aluminum wire, the result became a cheap and simple antenna for 70cm.
The pvc pipe is about 57″ end to end and is 5/8 diameter (you can use bigger, if thats in your junkbox) and then a couple of short pieces about 1/2″ used for the reflector and also the driven element. I also got a T pipe, as a “mastclamp” since the antenna only weighs a few ounzes ;)
Here are the element lengths: Reflector loop 28″ Driven loop 26 5/8″ Directors 11 3/4″ to 11 7/16″ in 1/16 steps….
Element spacing: R-DE 7″ DE-D1 5 1/4″ D1-D2 11″ D2-D3 5,85″ D3-D4 8,73″ D4-D5 8,73″ D5-D6 8,73″
I will bring it to the meeting, so if you have any questions, I’ll be more than happy to answer them.

Hi Lars, Nice antenna!

I have modeled and built many Yagi-Uda, Quad and Quagi antennas and they all work great! Quagis are my favorite on VHF/UHF/SHF with their small size and big gain.
Share more of your quagi antennas so others can join in the fun of building their own and being “radioactive”.
