Hi folks.............any recommendation for a good heat gun to be used for shrink wrapping would be appreciated. Also, good known sources for shrink wrap itself. 73 John K4NP ________________________
My 137' inv L, with the vertical portion at 66' and 20 on ground radials show the following data at the base of the antenna. Resonant at 1820 KHz.... Z......100 ohms L......9.5 uH C......900 pf SWR w
Hi Folks.... The vertical portion of my L goes up to 66' with the additional 68' going horizontally. I have 22 radials underneath it. They range from 20' to 68' in length. It is fed via a 1:1 current
Thank you to each of you who took the time to provide input to my L questions/situation. Many good comments were received. One chap (thanks Jim) suggested that I convert the L to a T using the same 6
Richard.... I recently ordered the 402X and received it within a week. Best bet is to call them on the phone. 73 John K4NP _______________________________________________ ____________________________
Anyone have hands on practical experience with a full wave loop on 40m in any configuration? Interested in feedback on a half-square as well. I have found it is VERY hard to beat a simple 1/2 wave ce
Hey guys.......thanks soooo much for all of the input. I'll give one a try and keep my 1/2 wave up to get a good comparison. 73 John K4NP _______________________________________________ _____________
Hi folks..... Can't remember where I used to buy the "1/4 mile" rolls of kinky (no, not that "kinky") copper clad steel wire. I think it was 22 gauge. This stuff was invisible at 30 or more feet, esp
Hey Folks.... Trying my valued resource once again. anyone know of an outlet for the above. Can't seem to locate any by internet browsing. Thanks, and 73.........John K4NP ___________________________
Hey folks.... I am very familiar with the "models". Does anyone have hands-on A/B experience with these two antennas that can share their actual findings? I'm talking in the 40M-20M range. 73 John K4
Thanks to all who provided responses on and off the reflector. So far, Jim Brown, K9YC is the only one who seems to have actual experience in A/B testing between the two antennas (horiz outperforms v
Hey guys.... Anyone have a recommendation on the most stealthy rope (Dacron, etc) I can use to hold up the ends of phased 1/2 wave verticals? I currently use 3/32" black Dacron. Anything thinner (i.e
Hello Steve... I think it's fair to remind folks that your "doublet" was configured as an inverted vee, not a flat top. IMHO, in that configuration, I would normally expect to see less gain than a fl
Hello.... I'm going to pick brains once again. I am familiar with the antenna models for these antennas. Does anyone have actual comparisons of a Delta Loop and 1/2 wave Dipole on 40 and 20 meters? A
Dan, thanks to you and the rest of the guys for the input. The modeling shows that a Delta Loop, properly fed for vertical polarization, has less side nulls than a dipole (at a good reasonable height
I see some of the self declared techie types are concerned about my motives for asking the question in the first place. So be it. I suggest that many of the answers posted are of benefit to others re
As new condition (really!), with factory ATU. Just returned from TT with all hardware and version 2 upgrades. Non-smoker. 2150......original Orion w/ATU. 73 John K4NP ________________________________
I need to use a lighter weight, relatively low loss 50 ohm cable fro a phasing project (1.8-14 MHz range). The published specs on 240 look good. I am most concerned about using it with the legal limi
Hey Folks.... Is there a reasonable and proper way to remove the foil in this stuff? It is almost embedded in the dielectric and I can't seem to remove it to my satisfaction. Thanks for any hints. 73
I have had BuryFlex for about two years now. Fifty feet is buried and the balance is above ground. I also use it for jumpers at the operating position. I like it. 73 John K4NP _______________________
