We've had for many years access to a non-live AM radio tower (by non-live, the antennas are mounted on the sides of the tower, insulated, look like long steel cables). For a long time we ran AC to the top, into a small choke/transformer (some little gizmo) that filtered the AM radio signal,

Doug, The only way to tell if using shielded cable would work is to try it. Every high-power (radio tower) situation is unique. Most tower problems occur on high-power FM towers where the FM frequency is close to the Ethernet frequency but problems can easily exist on AM towers too depending

One thing you might try is making an RF choke at the tower base coiling up the CAT5 and possibly even using a ferrite on it as well. Leon * Jack Unger wrote, On 1/3/2009 3:35 PM: Doug, The only way to tell if using shielded cable would work is to try it. Every high-power (radio tower)
