friends!
Finally found my next antenna project..a collinear dipole array for the 70cm US ham band.
The general idea:

I don’t have enough RG58 or LMR240 on hand to use for this, but I have a ton of RG8…would that be suitable?
One Answer
Good RG8 such as Belden 9913 has less loss than RG58 or LMR240, so as long as the thicker diameter doesn't cause you trouble, then it should work fine for your project.
