Re: Topband: Inverted L improvements - Part 3 (now with data)
Man, that seems awfully broad! Somewhere, you have losses, my friend. You ARE measuring directly at the feedpoint, aren't you? And with the antenna analyzer FLOATING (not touching you, the earth, or anything else)? FWIW, the K9YC choke I used was about 6 turns of RG-6 wound through 4 or 5 *stacked* 2.4" Type 31 Fair-rite cores, *directly at the feedpoint*. Photos linked to partway down the page at http://www.w0btu.com/160_meters.html. As you'll see, I'm an elevated radials man. Saves a lot of $ in radials lying directly on the earth. Also, please see w0btu.com/Optimum_number_of_ground_radials_vs_radial_length.html 73, Mike www.w0btu.com On Mon, Jan 21, 2019, 7:46 PM Todd Goins wrote: > Hello, > > Per many people's recommendations I added 800ft of radials today.

Jeff, K1ZM used to have a chart.

Todd, get on the contest and rock and roll. I don't know of anyone on 160m who has not given their antennas an iterative workout over time. Bet you will do just fine. RX is the tougher nut anyway.

Re: Topband: QRG on 160 in North and South America
Fish beacons are pretty random on when they show up. Heard one this morning on 1819.8. Called CQ for about an hour before sunrise. RA4LW had no copy on me. ZL and VK4 RBNs were hearing me pretty well - in the teens.

Thank You Guy for taking the time for all great the info. I have several pieces of RG400 none are long enough. I was an airfield electrician for CVG airport. Got some out of planes and some from the FAA I would demo stuff for them. I will be looking for some RG400 on the web to make a few proper chokes I guess I don't know as much abt chokes as I thought. I figured any old wire would do. I will reread K9YC papers on the subject. ''You can put your lifetime stash of RG400 in your will, and leave it to a younger local ham, who will appreciate it. :>)) That made me chuckle..when I die my kids will throw all my stuff in the trash... ;0 :) Love this reflector always learning here.
