Is there a picture here that can help http://www.k9ct.us/Photos/New%20Tower/index.htm _______________________________________________ _______________________________________________ TowerTalk mailing
I got mine from the wireman and it had extra inductance for 160m but I am sure that others have it. http://www.thewireman.com/baluns.html Mark N1UK _______________________________________________ ___
I have to agree there. I have a low 160m dipole (it works great on 30m hi hi) but I struggle with dx on 160m....I can just about make the Caribbean with it from North Carolina with 600 watts. I am lo
I have had some Amphenol ones in line for years and have had no issues with them. Mark N1UK My experience is not all 90 degree adapters are created equal. I had several 90 adapters inline a few years
I am planning something like this. What sort of capacitor do you need to use as the series feeding element.......a vacuum capacitor? Mark N1UK _______________________________________________ ________
Thanks for all the help on the series rf caps. I am thinking of putting up a 120 foot Rohn 45 tower which is insulated at the bottom, so that it becomes a 1/4 wave vertical. I would like to feed this
Thanks Jerry, I need to improve my modeling skills. Thanks for checking it out. Mark N1UK _______________________________________________ _______________________________________________ TowerTalk mai
he is probably one of those grunters,groaners and whistlers that you hear on the air..best ignored --Original Message-- _______________________________________________ _______________________________
Yes, if you are running 100 watts or less then take a good look at those magnetic loop antennas. They seem to work very well indeed. I worked an Italian station on 20m ssb and he was using a loop ant
Going from 100 watts to 1000 watts is 10bB measured in power dB (10xlog) Isn't the S-meter measuring voltage dB's (20xlog) Is that why I normally see a 20dB (voltage) S-meter increase when a station
I did some googling and found this http://www.k7nv.com/proppitch/ Mark N1UK --Original Message-- _______________________________________________ _______________________________________________ TowerT
People often use a sturdy door. I have glued and screwed together 2 sheets of 3/4 plywood, now that is very sturdy. You can also buy the heavy wooden panels that office tables are made from, on line.
and here is an example of a laminated office table top...1 1/4 inch thick and very sturdy. Edge glued might be even stronger than this material. Although comes finished with a laminated "formica" typ
I was given used office carpet tile and the beauty of it is that you shampoo it and wash it outside before even laying it down. I picked a nice sunny day and the tiles were dry in about 2 hours in th
I have heard that G-10/FR4 rod can be machined to make good insulators. There are some places on the web that will sell you the rod and also can do the machining for you http://www.jjorly.com/g10_rod
The consensus was to use solid FR4 G10 rod. These guys sell it and I believe that they can do the machining required. http://www.jjorly.com/g10_rod_rods.htm __________________________________________
agreed......I wouldn't put it on the roof...it will just rip the decking out if you let the pulling angle get too acute Mark N1UK _______________________________________________ _____________________
In the old days and I have seen it done, you could have 30 feet above the wall bracket. I have seen a small tri-bander such as a TA33JR. set up like that in Northern Illinois. How strong is it? I don
When I poured my Rohn 25 tower base in Rockford, there was a concrete guy who specialised in small quantities of concrete. One or two yards were within his norm and he would stay at the site for 30 m
