What is the standard practice for using temporary guys as a tower is going up or being taken down? Is there a document somewhere that hams could be referred to? Thanks, Pete ws4g -- FAQ on WWW: http:
I found box of new plastic parts for a KT34XA. I would like to know if I have enough parts to rebuild a KT34XA. I have 43 small blue caps, 2 large red boom caps, and 2 cans of bronze colored goop wit
We might get a chance to put a KT34XA on top of an existing 60' tower on top of an industial building. I believe the roof is metal under the top layer of roofing material and I believe the tower is c
This weekend I built a 10m dipole which is fed by 75 ohm coax (uses 75 ohm catv cable already in the building) . Since the 259 is designed for a 50 ohm system I am curious to know if it is useful whe
Thanks for the note Mike, It's a nice antenna analyzer from MFJ. They usually have ads in QST and other ham magazines. Also check: http://www.mfjenterprises.com It looks like the best way to tune my
There was just a post about verticals and a link to a study on vertical dipole modeling. I accidently lost the URL for the web page for this study. Can someone please mail it to me. Thanks, Pete ws4g
Hi, I want to know whether to use 50 or 75 ohm N connectors on some hardline. First some background might be helpful. As part of building our antenna system we are using some existing 3/4 inch hardli
Hi, Is there a dealer I can call to get specs and pictures of N connectors? Web pages would be of interest too. Thanks, Pete == Pete Brunet -- Austin, TX brunet@us.ibm.com, ws4g -- FAQ on WWW: http:/
What is a block splice? I've been told the existing catv cable we are going to use in the building were we are going to put a ham station has two long sections of 3/4 in 75 ohm hardline connected in
First of all Grian, don't assume anything. 3/4" hardline is big enough for you to measure the od of the inner conductor, and the id of the shield. Then get out your handbook and plug the figures int
Is it theoretically possible to have 10-40 + warc on one boom or one mast? Will the resonances of the various antennas cause too many problems? I have heard a few bad storys about the Mosley Pro ante
How do you determine how much windload is acceptable for a tower, e.g. a 65' Rohn 45 guyed at 25', 45' and 65'? Some example configurations being considered with various windloads are F12 C3+EF240230
If a TH11 or a F12 5BA were put on the same mast with a 402CD/30m dipole or a F12 EF240230 would there be detrimental interaction? We are thinking of using a 15 foot mast. The 30m dipole would be the
Thanks to all of you that responded to my queries concerning windload and 40-10m antennas. The info was very helpful and much appreciated. 73, Pete ws4g == Pete Brunet -- IBM Special Needs Systems, 1
I got a chance to look at a Rohn catalog. In the 45G section there is one windload chart that shows max wind loads of 32, 23.8, and 17 sq. ft. for 70, 80, and 90 mph. Then later on separate charts fo
Chad, Thanks for all the info. Based on what you said my '81 Rohn book shows that a 70' Rohn 45 guyed at two spots can handle 9.5 sq. feet of wind load at 70 mph. On the chart just before that one it
I asked the library to help me find EIA spec 222-F. They asked for the title. Does anyone know the title? Thanks, Pete == Pete Brunet -- IBM Special Needs Systems, 11400 Burnet Road, MS 9448, Austin,
My problem was not realizing that the first chart was for building bracketed towers. Since that results in a much higher wind load rating it would be interesting to know how much wind load figures im
What are the pros and cons of using a pier point bottom instead of burying a 5' tower section in concrete? Thanks, Pete == Pete Brunet - Austin, TX 78758 (512) 838-4594 voice, (512) 838-9367 fax, bru
Hi, I didn't get a response on my last note about wind load. Maybe I am getting into an unknown area. Here is a summary of those questions. These questions are related to Rohn 45. Since Rohn's wind l
