+1 for building instead of buying!

Magloop:

• I used the https://miguelvaca.github.io/vk3cpu/magloop.html calculator, using 1inch coaxial cable, and a soviet vacuum capacitor. picture here

Delta loop:

• for 6m, horizontal polarisation: feedpoint at the bottom, impedance match with quarter-wave length of 75Ohm TV coaxial cable.
• for 30m, vertical polarisation: feedpoint on the side, connected by symmetric line, and a 1:4 current balun.

Sorry I don't find pics for the delta loops. Please ask if you want more details!
