So? If they spec the antenna in PEP that suggests it's peak limited. If it's
average power limited, then they should say so. Apparently they did, after the
fact.

If you run this then the PEP is 1500W and the antenna is within spec. Wes N7WS ' On 12/7/2017 7:52 AM, Keith Dutson wrote:That sounds reasonable. You might want to contact SteppIR to helpdetect the problem.I was using a vertical antenna rated for 1500 watts, but it failedusing 1500 watts AM on 80 meters. SWR went very high causing amp (Alpha 87A) to fault. Manufacturer said it would not handle AM, only PEP. So much for my demonstration to a friend. <grin>73, Keith NM5G_______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
