[Elecraft] Open Wire Feed Line Arrestor Conclusion

Thanks to AC7AC, F5LCI, GM4ESD, K5VH, N2WN, W6FB, WB1DOG. For their comments on and off the reflector. I have changed my antenna from about 6 m of wire draped inside over a window frame and ground being the ground in an AC outlet, to an 26.8 m wire at 12 m high, center fed with 450 Ohm line.

Re: [Elecraft] Open Wire Feed Line Arrestor

Morning Ralph, Thank you for sharing the information about these devices, very interesting! I must confess that I have for decades used NEW sparkplugs with their gaps suitably set for the maximum peak RF voltage on the line, assuming a high VSWR, plus some, and with separate static drains

Re: [Elecraft] Open Wire Feed Line Arrestor

I used one for 5 or so years with a full wave 80m loop. It seemed to work well but I don't think I ever had a hit. I also had a knife switch, but in case I forgot to throw it or a storm snuck up on my, I had the ICE unit. On 1/5/06, Ralph Tyrrell [EMAIL PROTECTED] wrote: Still running my K1

[Elecraft] Open Wire Feed Line Arrestor

Hi Ty, I had some minor damage to my K2 from ESD in 2004. I didn't have any form of lightning protection at the time. I did purchase this device and haven't had any problems since. Of course, maybe I haven't had a nearby discharge, but didn't want to risk it again. My new shack has this

Re: [Elecraft] Open Wire Feed Line Arrestor

I would take this quite a bit farther. I use open-wire feed for two major reasons. 1) It is super low loss no matter the SWR, without fear of high voltages burning up the feedline, and, 2) (directly related to #1) the antenna becomes inherently broadband with a suitable balanced tuner

Re: [Elecraft] Open Wire Feed Line Arrestor

The device is stated to have toroid cores on each side of the line conductor so as to provide a DC short to the antenna side of the box. On the transmit side, it may be AC coupled, which is fine when the right size cap is used for RF. The cores with their windings act as RF chokes while

Still running my K1 (#1423) on inefficient low antennas. I have some trees that will give me good height 50-60' and orient the main lobe of a double extended zepp (14MHz) toward Oregon, take notice ECN. I have come across a device that will keep the antenna at near DC ground at all times.
