[TowerTalk] Coax loss. Has anybody measured it ?

[Peter Voelpel]

VF of RG-393 is .70 as with other PTFE coax.

The highest coax loss of my station is on 2m with .7db through LCF 158-50
with UCF78-50 pigtails, total length is 75m from antenna relay to antennas.
On all the HF bands attenuation is not higher then .5db where I use LCF
78-50 with SCF 12-50 pigtails on 10-40m and RG218 on 80m and 160m.

73

What baffles me is that 213 U per times calculator is 1.1 db per 100
feet...at  29 mhz, yet  RG-393 is 1.1 db per hundred ft.    213 has a single
copper braid.  393 has TWO silver plated braids.  213 has a 12 ga  CU
stranded center conductor.  393 has a silver stranded  center conductor.
VF on 213 is .66    VF on 393 is .69
