Just curious, I was thinking about making a franklin out of 3/16" copper brake hose - when abcd567 ran it through his calculations it was shown that the tube diameter was too great to make an effective antenna.
WE have had people on here making antennas out of varuios co-axial from unknown to LMR400 with varying degrees of success. I'm just wondering to what the external diameter of the shield on the co-ax has on the antenna performance - could it be that a nice fat lo-loss downlead is poor material for an antenna and something that is thinner (but of good qualirt so it has a known V) actually works better in this role.
