Hello everyone, I'm new to topband. Recently got on with a coaxial L at 55 feet and I'm sure that it's no surprise to all that the performance is mediocre, although I have worked 23 countries. Thinki

The T loaded will perform very similarly to the L loaded vertical in the vertical component is about the same and the T and L are about the same length -- one centered and the other offset. Generally

Rich, Try to get the current loop to appear at the connection to the flat top T. This can be done by modeling or in the old days we would just tape a small 6 volt bulb on a loop at the T. While runni

Jeez, I am just reacting to the thought of 260 feet of top loading on a vertical. It almost seems as though one is using a single wire feed line to feed an horizontal antenna. I may have to get out m

I agree with you 100 % Earl. I wouldn't want the highest current at the bend though. I believe that there would be too much current in the horizontal field. About 90 to 100 feet on each side would do

It's not how our antennas work, it's how we *think* they work that makes us feel good. to what that Maximum radiation resistance occurs when current integrated over the vertical section is as high as

Tod, I should have been more specific. Top loading with a T type marconi with a short vertical 60 foot down lead can be peaked to reasonable performance with a 75 foot (each side of center) flat top

"A interesting special case would be when the vertical segment is 130 feet. Now when one adds 130 foot legs for a T or L you are challenged with a feed point that should be rather high impedance. Pre

Just being a bit defensive, probably without need, I would like to assure the folks commenting on this topic that I did intend to say 'feed point impedance' and did not mean 'radiation resistance' in
