30W PoE injector
15.4W 802.3af PoE Switch
1.
Use 30W PoE power injector for testing.
2.
15.4W 802.3af SW: Standard POE Switch, 48V/375mA

Cable DC Resistance = DC Resistance of Cable Inner con DC
Resistance of Cable Shield
4.
Typically, regular resistance of RG6 is 13 Ω per 100m / 300ft
5.
Typically, regular resistance of RG59 is 17 Ω per 100m / 300ft
6.
Typically, regular resistance of RG11 is 4.9 Ω per 100m / 300ft
7.
Resistance of Low resistance RG6 is 3.7 Ω per 100m / 300ft
8.
Resistance of Low resistance RG11 is 2.4 Ω per 100m / 300ft
9.
DC cable resistance should include LAN UTP cable, 10 Ω per 100m / 300ft
(for standard PoE interface, CAT5e)
