If you are using wire why not use zinc ground clamps? Tin the copper wire where it does into the clamp. I have this on each tower leg using a solid #4 copper tinned wire to my ground field. Sill look
What about diecast zinc like this? https://www.amazon.com/Ground-Clamp-Water-Pipe-Rod/dp/B00UTKQ3PW/ref=sr_1_5? ie=UTF8&qid=1508181810&sr=8-5&keywords=zinc+ground+clamp 73, N2TK, Tony --Original Mess
Hi Mike, Just curious how much impact on performance if you keep the feedpoints the same height and follow the slope of the land? Anyone model this? The deer, sometimes as many as 13 sleep right behi
I have a wire 4-sq with elevated feed points around a 80? tower. The feed points are about 10? above ground. I have 5 radials on each vertical. The radials are 41?. There are two coils between the ra
Has anyone added a 100pf cap across Z2 to move up the frequency of the F/B curve? If so, can you tell the difference? If you added the cap is there anything special about the type of the cap? 73, N2T
Just learned of something new to me - soft start for air conditioners. As I will be replacing both air handlers and compressors this year and I have a whole house backup NG generator, you have tweake
Any feedback on how the Hamation 2X8 compares with the Array Solutions and 4O3A? The Hamation seems to have a nice interface with their ShackLAN-4 Control Center N2TK, Tony My statement is based on m
For jumpers in the shack what about RG-8X low loss with foil and braid shield that Davis RF lists? How does it compare to RG-400? The most power these jumpers would see is 100W. I use Buryflex from t
Keith, Tnx for info. Only interested n 160-6M here. I need to make up some jumpers. I have RG8X low loss cable already. Trying to find out if any reason to buy some RG400 instead. Most of the jumpers
Gedas, Tnx for the info. Looking on eBay I see several listings for RG400 from China. I had heard Harbour Industries in VT makes a high quality cable. Not sure about the stiff from China., N2TK, Tony
Tnx Gedas. Yeah, want to make sure it is the good stuff I get. N2TK, Tony Hi Tony. Harbour Industries is a HUGE leader in the world of high-temp, quality Teflon cables and wires etc. They are the one
Jim, Tnx for providing the data 73, N2TK, Tony Here's measured data for Harbor Industries RG400. k9yc.com/RG400DataMF-HF.png Data was obtained by S11 sweeps (1-30 MHz) using VNWA, exporting as S1P fi
Tnx everyone for all the input on coax for jumpers. Some great ideas and info. I bought 100 of Harbour Industries RG400. I didnt want to take a chance on imported cable. Also bought crimp PL-259s. I
Tnx Gedas for the info on utube. N2TK, Tony Great choice Tony, you won't regret it. Just do not skimp on the quality of the connectors. The termination of the shields to the shell is critical as to h
Have a question about the values of the choke to keep RF from the relay and the caps for coupling of the signal. In different products I see quite a bit of different values of both components. For th
Don, Tnx for the feedback and guidance. N2TK, Tony Being the original "inventor" of this circuitry, I can attest to using 2.5 mh chokes for low bands. For multi band use, I suggest TWO stages at each
Grant, How do you measure for self-resonance and how important is it for what I am doing? N2TK, Tony I have the same interest for a 160/80m relay switchable receive antenna feed design on RG6 and cam
Tnx Steve, Yes, receive only. I have separate runs of coax form each antenna. 73, N2TK, Tony Tony, My apologies. I re-read your email and see your dealing with receive only antennas. You may ignore m
Looking for a fiberglass enclosure about 20"H X 16"W X 8"D to mount on the tower to hold various terminals, relays, etc. Will add a grounded to the tower aluminum plate in the box for mounting compon
Tnx for all of the feedback I received. Took all of your input and taking a look at the boxes recommended available to make my decision. Lot of input in a very short time frame. Awesome. 73, N2TK, To
