Okay boys and girls. the antenna project is done I have a 160 meter doublet feed with 600 ohm line. 130ish feet on each side. Followed the antenna suggestions from everyone and now have it connected
Please define "doublet." Do you mean a single wire dipole, or do you mean a folded dipole? How high is the antenna? How long is the feedline? A single wire dipole has a feedpoint Z in the range of 40
Are you using any extra C connected to the rear terminals of the tuner? Likely needed if the high Z switch is in #5 position. The extra C is 1000 pf @ 500 V as provided by Tentec. I use 256 ft of wir
The TenTec 229/238 tuners have a shortfall on 160 meters because of the 470pf disc caps will not handle the currents involved. You should replace them with 470pf doorknob caps. I found them on ebay
bob and the group I didn't have the .001 in a voltage rating that would live so I used a .01, and yeah, I know that's way too much C for the instructions, it looks like the extra c is only used in po
The extra / external cap is used across the capacitor bank, starting at position #4 and #5. Both on the Low and High Z sides. I find the text is incorrect, the schematic is correct. Yes a .01 is way
Buy a wooden wine barrel, pour the contents into another container (for future use), and wrap the feedline around the barrel. BTW, I believe 1/8 wavelength on 160m is something more like 66 ft., not
bob and the gang, inserted the 259 and with the 1:1 balun. resonate freq is 2.487 or there abouts so the antenna as it sits is too short. I'll re-check the length with my harbor freight made in china
THAT'S THE PROBLEM, MIKE! (the Chinese have smaller feet than we do) bob and the gang, inserted the 259 and with the 1:1 balun. resonate freq is 2.487 or there abouts so the antenna as it sits is too
Sorry guys. I am using Yahoo and they are going thru a downgrade in their services. They have went from a working system to something a pre-schooler would dream up. Here is a link to the web site
Well, perhaps no... I added fifteen feet of wire on both ends, expecting a dramatic drop in resonance it went from 2.489 to 2.334 mhz something is wrong! Mike, WB8VGE SunLight Energy Systems The Heat
thanks for the link, but it take you to a website for loans Mike Bryce prosolar@sssnet.com _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.conte

that link works, but... I don't have a problem with it drifting once tuned, i can't find a tuning solution. still working on the problem Mike Bryce prosolar@sssnet.com On Oct 12, 2013, at 1:44 PM, Mi
What is nearby that could be affecting the antenna? My aluminum dipoles often exhibit strange, wild swings with a change in position in the yard. Something nearby may be coupling and affecting it. An
Thank goodness someone figured it out! Hi. I am expecting caps anyday now to mod my '229 tuner. Clayton I added fifteen feet of wire on both ends, expecting a dramatic drop in resonance it went from
Mike, THIS MIGHT BE YOUR PROBLEM: Maybe the antenna is already too long and its primary resonance on 160m is below 1.8 MHz, AND your analyzer won't tune down that low. The dip you are getting at 2.3
Hmmm... Maybe Mike ALSO has a friend with a different analyzer who can test it, also. More likely the difference in analyzer than a difference in yard stick ? -- K8JHR -- My suggestion is to have a s
Mike, I spent a LOT of time trying to help you, beginning with several questions to clarify exactly what it is that you have. You didn't bother to answer any of those questions. So I give up. 73, Jim
Jim, and all the others here on this list..... Sorry, I certainly wasn't neglecting you or anyone else trying to help with the doublet problem. With two computers running 24/7 and my iPad catching th
