I would also look at drilling the old concrete and putting in some concrete anchors or rebar that has been appropriately bend. In addition to the chemical treatments, this will help with the mechanic
As an aside - I had absolutely no problems getting a new capacitor from them - I had one for the high part of the band - and needed on for the DX window - I called, and sent in my check - it arrived
Can you take pictures of the fracture surfaces of the bolts - really good close ups? I may be able to take a look and tell you why - fatigue, overload or?... Scott --Original Message-- From: towertal
That is not quite true. It depends on the height and load rating. From the Rohn Catalog (Revised 2004), Dwg # A871266R, 25G is self supporting, and they provide the allowable loading and height....Fo
That is absolutely true - a larger base is needed. But I was just putting my 2 cents worth regarding the self-supporting 25G And yoiu forgot to mention a totally different Rohn drawing for the free s
Bracketing makes all the difference in the world. Looking at the Rohn catalog, it makes a huge difference in the load carrying capacity whether they are freestanding or bracketed. Your results do not
Follow the manufacturers instructions, and unguyed RG25 is acceptable. Obviously, free standing to 70+ feet does not meet the manufacturers recommendation. Rohn 25G can be self supporting per the man
What size would you suggest for 80M? --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] On Behalf Of Richard (Rick) Karlquist Sent: Tuesday, January
There was an article in QST several years ago, where they indicated that it was rated for AM service with a lot of extra heft for additional safety.... I think you will find that they were rated for
You need to check the serial number on the bottom of the rotor. I trashed my rotor (series II) by using a newer (series III box). I just got a NOS CD-44 with controller at the Timonium Hamfest, and I
Spend the money and buy a stamp...At least on the East Coast there is reciprocity for most stuff - but California doesn't accept other PE paper as valid - so others do not consider California stamps
If you can't put up a full size 4 square array with at least 5 miles of radial field - you are wasting your time and any one else that will have to try and hear your puny signal. It is a waste of mon
That was what I was told - that I would be wasting my time and time of everyone else by putting up a simple vertical on 80M. Then I guess I've been wasting my time working 192 countries on 75m with a
Actually the website is out of date. It is approximately 285 countries, and 7000 contacts. I believe you misread it. Not as many as those here. However as I have been told here numerous times - anyth
I think the you are the only one to have gotten it correct..... I think the problem is that sarcasm doesn't work well in print, guys ;-) contacts on 80M using a Gap Titan I don't believe you have an
A lot depends on where they got the patents. For instance, if they got the patents in only the US, then I don't think it would be valid in Europe. I know when we file a patent, it is filed in Eu, US
Gentlemen: I have modified an old CC 215WB 2M beam which was purchased used. Previously, it used to have a triagonal reflector. It was previously modified using a more conventional single reflector.
Thanks Ralph. I have the manual - I was able to download it. One issue that I have, is that I substantially modified the antenna. The only thing I kept was the matching section and the driven element
Thank you John. The antenna in question is not a split element design - it uses a ingle element with a delta match. Something like: __________________ -- Where one leg is the shield and one side is t
