Attic antenna is frying my 2nd floor LEDs
Due to small house+small lot I don't really have an outdoor option for a (permanent) antenna. Ok, fine, I've been doing the attic antenna thing for a little while now (originally a dipole, now using a cobweb). Not ideal, but the antenna basically works. The current problem is the antenna is occasionally causing problems with the LED bulbs in the 2nd floor bathroom. The light+shower vent has a circuit board of LEDs acting as one of the bathroom lights. At one point when I started to transmit SSB on 17m, I heard a faint pop noise from the bathroom. So that light is fried (the vent fan still works fine). Also elsewhere in the bathroom there are a pair of regular screw-in bulbs, and I've already gone thru 2 different LED bulbs as they will start just flickering randomly. I'm currently experimenting with CFLs since presumably the circuitry is somewhat different and might be more resistant to RF (maybe). I haven't fried those yet.
The presumption is the RF is hitting the power wires and is causing the problem. I'm wondering if I try to create some inductance near the light sources would solve the problem. I have various ferrites and toroids lying around, and I'm experimenting wrapping some 14 gauge THHN wire around some clip-ons as pictured (using some unspecified ferrite type). The idea is to splice this in near the vent, and another set of wraps near the other light fixture. I've got some type 77 toroids, and can get other kinds if needed. I'm only playing with spooled wire at this point, I haven't installed anything so far. I haven't even looked yet to see how much room I have to install more conduit.
I'm running a Yaesu FT-710 at 100 watts, and would prefer not to lower that since I'm surely losing a little bit of power just pushing the signal thru the roof. Has anyone else solved this particular problem? Am I barking up the wrong tree?
