Just for the heck of it, I pulled an old (maybe 20 years?) 20 ft length of a no-name, foam dielect; /archives//html/Towertalk/1998-07/msg00042.html (7,840 bytes)

There is a rule of thumb that Insertion Loss is roughly equal to one half the Return Loss; /archives//html/Towertalk/1998-07/msg00044.html (9,032 bytes)

Either way, 20 ft is probably too short to get a good test. We use it a lot here on incoming inspections, and the thing c; /archives//html/Towertalk/1998-07/msg00053.html (9,594 bytes)

At 28 Mhz, according to their formula, my loss was 1.3 db and at 7 Mhz it was 0.7 db!
