Just had tilted over the tower to replace some antennas. Checked the coax
for loss. Measured the power going into the coax and measured the power at
the end of the coax at 28.0 MHz with a dummy load on the coax. Used the same
watt meter for both. The length of the coaxes is about 210 - 230'. Here is
the loss as a percentage of power out/power in.
By the way, I cut off the end of one of the 9913 runs at the house (lowest
point of run) to see if any discoloration of the copper. There was none.
This coax has been up for 8 years.
7/8" Prodelin hardline - 88%
1/2" Prodelin hardline - 82% - 2 runs measured the same
9913 - 68% - 2 runs measured the same
RG-213 - 65%.
The measurements are approximate and were done to just check to make sure
the coax didn't have a problem.

While I agree that 9913 is probably not the best choice out there...I
have to say that I had 2 runs of 9913 up for about 3 years. When I
replaced it with hardline, I cut open the cable in a couple of places
and there was no water inside the cable.
9913 is not bad cable...you just have to be extra careful sealing
connectors & making sure there are no nicks or cuts anywhere to let H2O
in.
