This is a fascinating area for sure. I have a 300' microwave tower 600' from my residence here and feel pretty snorky about being safe.
1. 20 mm MOVS I chose 180 volts as a withstand voltage peak to peak
2. Avalanche rectifiers. I chose 170 withstand volts.
3. GDT 180 volts for me. Line to neutral, line to earth ground.
4. Rice grain fuses. 2-amp limit, 5-amp surge.
5. Duplicate )paralleled) MOVS line to neutral, line to earth ground
6. Duplicate (paralleled) TVS diodes again line to neutral line to earth ground.
7. I reinforced the MOV effect with 10mm devices 190 volts
Most if not all the devices are from one Chinese company on eBay. Origin Singapore and Thailand.
Devices should be qualified according to prevailing line value conditions. Down here, 127vac is the standard. 132vac RMS is not uncommon. Before someone else jumps in with a yowl about peak-to-peak exceeding device ratings I invite them to understand my device has been in circuit for three weeks now. No rice grain fuses blown, no devices found open or shorted as of this morning.
I WANT MY TEKTRONIX!!!!! I feel naked without it. By god and by hook or crook I am going to lay hands on my own personal scope meter. This is 10MHz work not 500 MHz!
My umbilical is a concrete house thickly laced with rebar. From one of the foundation rods, a 1 gauge AL powerline snakes up the hill and connects to a 3,000 gallon concrete reservoir which leaks just enough to keep the ground beneath damp. If a bolt gets past all that it can have me...
