Hi Jim, You are probably right. Especially as I am using a lot more than 25 feet of wire. (Remembered it wrong). I found that is was way more efficient to add a bunch of ferrite beads on the coax bet
How about taking a Variac transformer, adding a full wave rectifier bridge and connect that to the drill. Series connected motors work a lot better on DC than AC. You can better torque that way. Just
I was told that tubes are for structure, that is they are made to be strong structurally. Pipes are for transfer of liquids are are built to be able to contain whatever you pass trough them. You can
Both were used. Many times a manufacturer used the dBi without telling as the numbers looked better. To make figures looking even better the numbers were also many times "padded". I, many times, saw
dBi, (gain over isotropic antenna) refers to something that radiates equal in ALL directions. (If you cross two dipoles and feed them 90 degrees out of phase, you get something very close.) The dipol
I believe with a dielectric constant around 80 the water surface will act as a good reflector especially as the graze angle is small. This is the same way as glass can reflect light and is regardless
Funny you mentioned it; how much better is a coil (or helical) be if it is made of ribbon wire instead of round wire, or is it worse? Hans - N2JFS of the Helical effective coil favorable (and hence *
You probably don't have to bother wrapping the inner conductor together or to teh shield as most possible the shield will take care of all current. Wrapping them together won't hurt though. 73 de Han
Hi Dennis, If my memory serves me right you have the right combination. I believe the "M" stands for "receiver" and the "G" should stand for "transmitter". The are military specifications that totall
Trying to dechiffer the formula with my rather rusty knowledge, I see a radiating system (yes, antenna) there you, by exiting the conductors in different places manage to generate two different anten
One thing everyone seems to forget is how to get the wave out of the dielectrics after it is generated by the very much smaller antenna. You could reduce the size major if you surround it with water
I believe you might get some corrosion as you have a mix of metals, copper and tin and that might lead to a breakdown after a few years unprotected but a metal breaking down from UV light, now way. E
This is one of the few times I state: Why buy if you can build". I do that and it is not that complicated. If you have a drill of some sort all you need is some (no even high tech) plastic and wires.
You have a 50% tin, 50% lead solder with flux included. Generally used for soldering of electronics. You will have the "usual" degradation from corrosion if you don't protect the connector from moist
Hi Ken, Crimp is the the answer. You can make it ever better by adding some shrink tube over the wire next to the crimp connector. You will reduce the stress on the wire even more that way. May be a
Hi, If I remember it right, Dave, K1TTT has a tower up without any base, just a base plate right on the ground and a set of guy wires. Right, Dave? Hans - N2JFS --Original Message-- From: Doug Renwic
John, What's the web site you are sending us to? I see no tower but a lot of promotional stuff that has nothing to do with towers. A hidden button somewhere? Hans - N2JFS --Original Message-- From: j
I believe you have bamboo growing in a good part of Alabama. My son was living in Tuscaloosa for some time and told me you easily could find 15 ' bamboo sticks around, free to harvest. You do have to
I have a used tower in my back yard. It was used as a crank-up in the past but I have the possibilities to put it up as a fixed tower and don't need the maintenance problems with a crank-up. The winc
That's what I suspected. Is there any way to get these sections from Heights or can I use the section I can buy from Universal, or is there someone out there that happens to have them "laying around"
