[Elecraft] Stealth antenna insulators

[WILLIS COOKE]

I have no requirement for stealth because I live on five acres in the country.  I would speculate that a big factor would be if you are using low, medium or high power and if it is raining or high humidity.  Traps in multi-band antennas are designed for a few hundred ohms so I would think that a wet string that still has a few hundred ohms should perform very well.  I would have no reservations about connecting a QRP rig and would feel OK with 100 watts.  I would be careful with connecting a multi-kilobuck amplifier to a string.
