Mr. Weir is at times given to hyperbole, but I love his articles. I
just rigged up one of these puppies, and VSWR takes at 5% hit.
There's easily detectable RF leakage near the contraption also. I
don't have no $25,000 in the bench, but ironically the VHF Comm test
rig is one of Jim's old kits. Anyway, a few % is tolerable if one so
insists, but there should be a bit more loss in feeding the handheld
with an audio connector. Still should improve on the ducky.
Best,
Fred F.
