I remember seeing this before a couple of times, but thank you for reminding us all of it. I feel this reminder was most timely. I dare say other models of power supply might benefit from the same mo
Well....yes and no. Yes, a circuit exists through your radio gear that ties the two grounds together. Depending on the equipment, it might even be a pretty good connection, although not at RF. But if
Although I don't know if my system, or anyone's system could really take the full brunt of a direct strike (although I know several have claimed so), I do agree that even a few tenth's of an ohm of r
Or....a half wave ground wire, to repeat the low impedance at earth right at the radio. And, since lightning is RF, I feel that a real RF ground is important, even for lightning. 73 de Gary, AA2IZ
Well.....If I had appreciable amounts of RF on the outside of my coax, which I don't due to the heavy chokes I use at the ends, then I can imagine a path for RF to flow from my power amplifier into t
See my other reply on this subject. No source, in my setup, for any appreciable current to flow on this ground path. No more than there normally is on anyone's ground path. Of course, as has been wri
station the close But, as you also said, there should be no current in it. I don't advocate using the half wave ground in a vacuum, that is, without taking the other necessary steps also. You must ch
Hehehehee.....I think that "put in a load" meant he did a load of wash....not inserted a dummy load in the antenna line. Of course I could be wrong. 73 de Gary. AA2IZ fact That's a The ham RF to comp
Jim, Thank you for informing me. I will avoid the use of the "c" word in future. Of course I have seen far worse on the list, but I assume all those folks were placed on moderated status as well. I s
I also use the 135 ft Dipole fed with ladder line. It gives me just excellent results. I use other antennas and feedlines as well, and my experience has been that with a proper setup of the entire st
Well, Bob has it in a nutshell. If everything is balanced, then basic physics rules, as always, and the equal and opposite fields set up by the equal and opposite currents in the feeder will cancel a
Of course, one must not forget that, feedline notwithstanding, the antenna Does radiate (we all hope). So I guess maybe 5kw 5 feet away from anything whatsoever might be a problem. Now on the other h
One certainly needs a tuner if one is going to connect the 50 ohm output of a modern solid state rig to the high impedance at the end of a half wave antenna. Of course this is done all the time. I re
Me too. I still have a multi-band vertical up, but of course its not a half wave dipole. Even so, it compares reasonably well with my beam. (That is, the beam is better, but not by an overwhelming ma
Ok, lets get this straight before I get confused again :) :) I got out my Carr Lane book of "Handy Multipliers and Trigonometry Tables for Engineers" which my Dad gave me back in 1968. It lists the c
Yes indeed. Or one could go back and speak to Mr. Marconi himself, for whom the vertical antenna bearing his name was of course, well, er, named. :) Your point (and others) being that the vertical an
OK, now that I wrote this I see that the issue had already been corrected and set to rest. I did not mean to beat a dead horse and apologize for having said it yet again, after it was already settled
