Hi Jim, I have experience with 7/8" Heliax water condensation inside the center conductor. In my case, I found that wrapping the center pin threads with a couple of layers of teflon plumbers tape bef
Jim, these are the same issues that come up with mobile HF antennas and various loading methods. All of the techniques you mentioned will make the element electrically longer and that is what you are
Steve, I guess I don't understand why you think concrete will stick to the forms? And if it does, why is that a problem unless you are planning to take them back to the lumber store for a refund when
Hi Barry, I have no actual experience with this but common sense says that the answer depends entirely on the resonant frequency of the central structure. If it is resonant at 1.825 MHz, there just H
Peter, you might want to look at the pdf copy of the original article. There is no "trap" per se in the design. Instead, there is a clever arrangement using a parallel LC circuit that provides induct
Just curious here; were the broken wires at a soldered connection? 73, Gerald K5GW In a message dated 12/16/2010 11:28:26 A.M. Central Standard Time, greenacres113@charter.net writes: I have a proble
Quarter wave baluns are used extensively in VHF/UHF applications. There two variations, one using a coax of an impedance needed for desired impedance matching and surrounded by a sleeve connected to
For Towertalk readers: Texas Towers is offering 26 sections of 55G tower at a 45G price. A total of 26 sections are being offered at $269 each, first come, first served. These are new, 2010 manufactu
Just a bit of pencil scratching on the back of an envelope shows a base like this to be far from overkill, especially considering it is based on "normal" soil. When I drive a medium sized tractor aro
Jari, what is so special about the bad potentiometer that it defies substitution? 73, Gerald K5GW In a message dated 1/31/2011 2:42:10 A.M. Central Standard Time, jari.jussila@oh2bu.pp.fi writes: I h
Scott, that sounds like a great idea! Now, how can one add wireless transmission to get those pulse back to the shack? I need capability to transmit pulses over a distance of about 600 feet? I bet so
Jim, many thanks for the tips! Linx has two way rf modules listed and that will allow direction control as well as remote direction sensing. I can see the possibility of installing a rechargeable bat
Perhaps this will initiate some action to further expand the SSB segment of the band down into part of the mostly unused cw segment. Long overdue in my opinion. How to make this antenna/tower relevan
One cu ft = 12 X 12 X 12 cubic inches or 1728 cubic inches. If i.d. of tube is 4 inches, area is 2 X 2 X PI = 12.57 sq inches. Total volume for 40 ft length is 12.57 X 12 X 40 = 6031.85 cubic inches.
Another useful feature of hose clamps is their tendency to keep ice from sliding down the element as it melts. At first thought, this may seem like a bad thing, but when ice slides down a drooping el
To point out the obvious: Sometimes temporary guys are attached to temporary anchors and they may be a lot closer to the tower than the recommended 80% figure for permanent guys. This reduces the guy
Art, How much lean are you seeing? There are number of possible solutions depending on your capabilities and how much time and $$ you are willing to spend. 73, Gerald K5GW In a message dated 4/17/201
John, a broken boom will not be perfectly round at the fracture point. You may well need the extra space the .048 material will provide. I suggest you use the available .048" material, cut a couple o
