Re: Topband: 160 4 square

Hello All JC, Greg knows quite a bit about receiving on 160 meters as he has had a Hi-Z 8 element array for some years now. Actually he has done quite well with it. Especially when he was neighbors with our dear departed friend N4NN in Florida. JC, I have a question. If the Waller flag d

Re: Topband: 160 4 square

HI Greg You need to detune the tower and the 4 square will work fine. But if you want to have a good RX you need a Horizontal Waller Flag at 140ft or more. You can see the two webinars about Waller Flag at www.wwrof.org archives http://wwrof.org/webinar-archive/n4is-waller-flag-construction/

Re: Topband: old telephone line insulators

I find that figure 8 glass insulators I buy on e-bay work very well and give my wire antennas a bit more of a professional look and of course will last a lot longer than the wire.  Plus I like the old school look too.  Russ  K5ZZR   My Heroes Wear Combat Boots!  Nothing can stop the man with the

consider buying k1zm's book on 160 you now have enough land to build every antenna in it. n4fx -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Jorge Diez (CX6VM-CW5W) Sent: Sunday, August 27, 2017 12:32 PM To: gary mankoff Cc: topband@contesting.com

Many thanks to all who offered input and ideas. I'll let you know how things come out after we get the system together next month. 73, Greg-N4CC _ Topband Reflector Archives - http://www.contesting.com/_topband

Topband: 3YØ and KH1 on 160m

Efforts by two teams of highly seasoned and experienced DXpeditioners are well underway to put both Bouvet and Baker-Howland in your 160m log in 2018. Pent up demand for both is great. They are #2 and #4 respectively, on the current overall DXCC most wanted list. The 3YØZ team plans to be on th

Re: Topband: old telephone line insulators

I witnessed the collectors at the auction. There were three other boxes of those scattered through the auction site. The collectors bid them up to astronomical prices. These were overlooked and the collectors were napping when they came up :) They are at the tops of electric utility poles on th

Re: Topband: Best 160 antenna

I have 90 ft trees and I have a 1/4 wave draped over the top of them. I have gone with elevated radials and in ground radials at different times. I have a unun in place and a choke to provide a DC ground as well. I'm pretty pleased with the DX I've worked with it. I have used both a Drone and

Re: Topband: Best 160 antenna

I’ve found it useful to put a ferrite choke balun at each end – one at the antenna and one at the receiver. Jim Brown, K9YC, has some helpful stuff on the internet about this. Sent from Mail for Windows 10 From: Mike Waters

Sure they work. Some years ago there was a craze on collecting these and they wouldn't have lasted long in the field at a height that could be reached! N0UU _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: 160 4 square

Take a look at the K3LR website.  This is essentially what Tim does, only instead of a 4-square, his array is a 5 element parasitic array with three active elements.  K3LR just gave a presentation on his station this weekend for the Society of Midwest Contesters and this was mentioned. 73, Gar

Your tower may act as a reflector if ground at the base . If un-grounded,, then no problem. Could take many hours on the tower to work out problems. Its easier to spend the hours with a modeling program while on the ground. W7EL Roy Lewallen P.O. box 66958 Beaverton, OR 97007 Roy sells ant

Re: Topband: Best 160 antenna

Also try an Inverted L and elevated radials (4-6 100 ft) for 160 & 80M. See the QST 2012 article by Scott, K4VWK. I am using this antenna now and for the past two yrs w/ great success. Good luck - Alan K9MBQ -Original Message- >From: "Jorge Diez (CX6VM-CW5W)" >Sent: Aug 27, 2017 12:31 P

Re: Topband: Best 160 antenna

The importance of a ferrite choke balun at the feedpoint cannot be overemphasized. A good design for 160m is 5 or 6 turns of coax wound through five stacked 2.4" 31-material ferrite toroids. Photos and details on my web pages referenced earlier. I had two elevated radials. It is a well-established

Question for the group... >From a 140 foot freestanding tower, I will suspend 4 pieces of phillystran 90 degrees apart from the top of the tower. Antenna wire will be attached to the phillystran such that verticals will be dropped to create a 4 square. I will have as much vertical length as pract

Re: Topband: Best 160 antenna

Hi Gary, For many years I used an inverted L between two tall pine trees and one elevated radial that was L shaped to fit on the 90' x 60' lot I had in Spring, TX. The radial was about 15' up and it was fed through a choke balun. Worked about 160 countries with 600 watts output. I also had an AY

Re: Topband: Best 160 antenna

Gary, I've compiled some useful information about this at www.w0btu.com/160_meters.html. Maybe you can use those trees as supports for a few elevated radials under an inverted-L! Scroll down to the links part at www.w0btu.com/Optimum_number_of_ground_radials_vs_radial_length.html 73, Mike www.w0
