Comm-Scope? P-I or P-III? TFC? T-4? Trilogy?
I have the spec's on most hardline and it doesn't vary
much from brand to brand. Trilogy is air dielectric, however.
Comm-Scope has their spec's on their website.
At 450 mHz (millihertz) loss isn't a factor. At 450 MHz
(megahertz), it is. At 1800 kHz, it isn't unless that was
1.8 GHz or gHz. IEEE says I believe that all
magnitudes are lower case except for m for milli
and M for mega.

Subject: [TowerTalk] 75 Ohm hardline losses ?
Anyone have a chart of the losses of 75ohm hardlines?
I have several different sizes from 425 up to 750. I will be
using them on freqs from 450mhz to 1.8mhz. Would like to see
a chart of what my losses will be per 100', per freq, per size.
Also I'd like to know the velocity factor of each size as well.
Thanks in advanced......
