Locked Re: Indoor antenna question
It makes no difference to the performance of the antenna if the wire used is coated or bare. However, if you're using it inside then you really want that nice plastic covering! Also same with the wire

Hi Jeff: You may use your wife for a form to hold the 1,000 feet of number 12 awg solid wire, and place it next to the window closest to your Collins. You'll get great reception with no hassles from

Locked Indoor antenna question
A couple general antenna questions - is bare wire to be preferred to plastic coated wire? Thicker wire better than thinner? I own a Collins 51J-3. I'm using about 20 feet of ordinary speaker

Locked Re: RG-8/RG-213 voltage rating
I have used RG213 to approximately 10,000 volts to feed power to the anode choke of a driver stage in a high power transmitter operating in the HF bands. At this voltage level, the breakdown points

Ditto! In 6 weeks you will have enough oxidation built up around those joints that the transmit efficiency will drop like a stone. Connection resistance on transmitting loops needs to be held to an

Jerome, I have been using degaussing coils as VLF (sub 30KHz) antennas for reception of sferics. They work very well down low. With the ~0.047 uF input capacitance of my AD620 preamp the coil

Locked Re: RG-8/RG-213 voltage rating
One problem with using RG-8 or RG-213 coax as a capacitor and lowers the voltage rating is the shield. When it's cut you have many sharp copper wire ends that greatly increases the probability that

I read at this link... http://www.thewireman.com/coaxdata.pdf ... that the voltage rating for RG-8 and RG-213 is 4000V and 3700V. I don't know if anyone else can verify these facts. If this is the
