Wes cut his radial length to match the vertical L section height (see N6LF I didnt think it was the shortening OF the length of the radials that would improve performance e.g. going from 10 125 radia
Way back some where around the original posting did he not say he had 2 160 antennas up and they are close to each other? a short vertical and this antenna? If so what is the short vertical doing,

Meant to say should not decrease loss ... Sorry! Bob AA6VB Sent from my iPhone _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
Al Christman K3LC thoroughly sliced and diced the tradeoffs of number vs length for given total wire investment is his Mar/Apr 2004 NCJ paper. N6LF also has a lot to say. Grant KZ1W I didnt think it
What is missing from that discussion about a maximized use of a given investment, is whether that investment however well maximized, is in fact adequate for the particular ground characteristics and
It's possible that the K9YC choke was improperly wound, per my forwarded message from Jim here yesterday. Here is K9YC's updated info on choke baluns. http://k9yc.com/2018Cookbook.pdf 73, Mike www.w0
Your "apparent" and mine are different because it isn't apparent to me that I advocated that. I offered a possible explanation to what Todd is observing and provided the title of a reference source
Regarding the choke construction and implementation. Mike and I have had an offline exchange, with pictures, and I think we have agreed that the choke has been constructed properly per the newest K9Y
Both Merv and Guy are correct here. Perhaps this antenna doesn't ever have a chance at being any good due to the suburban area and lot size that I'm constrained by. Within a 250ft radius (huge!) ther
Todd, dont get discouraged and dont let lot size fool you....I'm in a subdivision, 80x180 ft lot, with a 50ft tower, hygain hytower for 75/80m (also works as a second radio antenna), and 2L 40m phase
Spooks! Haunted soil! ;-) That's probably not the problem. As I mentioned privately, I think uploading some more photos to a free file-sharing service website *and sharing those links here* would hel
I worked 160m for a few years when living in a townhome. The antenna was a trap loaded attic mounted dipole that ran through holes in the ceiling and down the walls to the ground. Had a lot of 160m
Hi Todd, In my opinion you're giving up too easily on your tall antenna. I suggest that you focus more on evaluating its on-the-air performance , and not focus as intently its feed point impedance an
Hey Todd, What happens to your Inverted L's SWR curve if you short your other 160m antenna (the 43'-T) to ground, or otherwise detune it somehow?..could be you're onto something..not sure. Wide SWR's
As always Frank makes good points. In my case my one lowly tower is 90 feet from the inverted-L and in fact supports the horizontal wire. It's much too short to exhibit any resonance near topband,
Dont get discouraged by all this for sure What I see as fly in the ointment is another 160 antenna close by with another radial system, Anyone of you gurus ever figure what putting power into a 160 a
Okay, after many requests, on and off list, I disconnected the 43' T 160m antenna at its feed point and for good measure I disconnected the coax feedline from the system too. It made a pretty substan
Disconnect the other antenna. Let it float. 73/jeff/ac0c alpha-charlie-zero-charlie www.ac0c.com It made a pretty substantial difference in the measurements. The 1.5 SWR range is now only about 35 k
