Antenna and power

[N2CHX]

Hello everyone, haven't been here for a while. My question is.... I have an Arrow 4 element beam for 2 meters. It is rated at 150 watts, Do you think I would hurt anything if I ran 300 watts thru it ? :cool2:

Depends on several factors and the most likely scenario is breakdown of insulation at a high impedance point inside the antenna somewhere.

First, did the manufacturer rate it conservatively? (an unknown, most likely). Second, what kind of modulation and duty cycle would you be using? Third, depends on how well tuned it is. Higher VSWR will increase the chances of something flashing over. Fourth, depends a little on your elevation and relative humidity. and fifth, why would you want to? You're not going to gain a whole lot in the grand scheme of things.
