A 75 Ω coaxial cable for RG11 drop lines, with gel as its third outer element. The gel sits over the aluminum braid and AP tape shields and readies the cable for outdoor conditions.
Jelfill
A third layer against moisture
The third outer element is gel, sealing over the AP tape and the aluminum braid.
75Ω
Impedance matched to drop lines
The characteristic impedance stays within 75 ± 3 Ω and limits reflection along the run.
7.92mm
Aluminum braid shielding
The 77% aluminum braid closes at 7.92 mm and suppresses outside interference.
13.88dB
Loss at the top of the band
At 1000 MHz the loss over 100 meters is 13.88 dB, dropping to 1.18 dB at 5 MHz.
20dB
Structural return loss
The manufacturer gives an SRL figure of 20 dB across the 5 ~ 1000 MHz range.
1.63mm
Copper-clad steel inner conductor
The inner conductor is 1.63 mm copper-clad steel and carries the run mechanically.
Attenuation values depend on temperature; the manufacturer reports a shift of 0.1% – 0.18% per °C.
