I'm putting a Balun Design 1115t on an A4s. Here is the Ozarks, we have *lightning!* But I want to put a resistor across the antenna side to drain off any static that develops across the un-grounded
No. Then they are outside in the weather and sun. Thanks for the suggestion. 73, Jim W7rY 73 Peter, DJ7WW I'm putting a Balun Design 1115t on an A4s. Here is the Ozarks, we have *lightning!* But I wa

Now that is what I was looking for! An actual spec of what the choke is and is what it's wound on! Thanks Jim 73, Jim W7RY On 7/1/2022 12:26 PM, jim.thom jim.thom@telus.net wrote: _*A 35-45 uh coil
Agreed. RG-400 works well to. The only difference between RG-142 and RG-400, is that RG-400 has a stranded center conductor. RG-142 has a silver plated solid hard drawn copper center conductor. 73, J

Is there a choke between the ground plane and the center conductor? An ohm meter will confirm. Hygain was famous for that. 73, Jim w7ry _______________________________________________ _______________
Which one is that? Jim, w7ry _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.co
As I said before. It's a choke. To provide a DC path to ground for static. 73, Jim. W7RY _______________________________________________ _______________________________________________ TowerTalk mail
If your referring to standard Schedule 40 water pipe, you would be correct. But as others have opined here, there is allot more types of pipe than water pipe. 73, Jim W7RY I used I beam material rath

There have always been two of them on the antennas I've installed the last 40+ years. 73, Jim W7RY No doubt they added a 2nd hose clamp because the first one was ultimately inadequate to the task. 73

Folks.. What Yaesu control box can be used on a G800 SA rotor for computer control of it? Can you use a DXA or SDX controller (with the ERC RS-232/USB kit) on a G800 SA rotor? Asking for a friend...
Not an option. Jim W7RY On the advice of contesting friends, I just bought Green Heron to control my Yaesu rotator. I love it! 73, Jim K9YC _______________________________________________ ___________
