Doesn't putting salt in the soil contaminate it so nothing will grow there? Does it seep into the water table? If so, it does not seem very environmentally friendly to me. Does the EPA have a stand o
A friend of mine just gave me a bunch (guessing 200' - 400') of hardline in about 6-8 pieces. Some pieces with connectors some without. So I plan to use this on two VHF antennas, and on a separate UH
I do not know what it is. I do not see any writing on the cable. It is 1/2" in diameter. The shield is solid and is silver colored. The inside conductor also looks silver colored as opposed to copper
The lead does not evaporate when you solder, the soldering iron is not hot enough to evaporate lead. Lead does not enter through the skin, It can enter through cuts or most likely through ingesting i
I am rather new, but I do not understand what you are asking for. First I do not know what a "small prop pitch" is. I am guessing you are adjusting the pitch of a propeller, but that does not make se

ANTENNAX sells a CD of the website. The snap shot is from December each year. So It will not be "gone and lost forever". Unlike some other places. I was annoyed when Needhams suddenly closed shop. Al
There is a difference between a house foundation and a tower foundation. The biggest difference being size. A house foundation may have 3000 square feet of contact with the soil for a UFER ground. Yo
I can answer the diode question. It is generally good practice to put a diode across the relay because of the inductive spike when turning it off. I have seen the spike go 3-4X the input voltage. If
I had never heard of that before. The ULN2003 is a seven darlington switch and has the diode built in. Also MOSFETS usually have the diode built into the switch for the diode in parallel with the swi
Carrying current IS the whole issue. If they were not carrying current then it does not matter how fast the contacts close or open. The goal of the applications note was to minimize the contact arcin

Sorry, I did not remember seeing anything on how to build your own ladder line. If he had just said check out the ARRL books it would give me a direction. Googling it, I found that you can make your

Last weekend a house in my father-in-laws subdivision was hit by lightning and was totaled even though 4 fire stations were on the scene. None of the houses around have lightning rods and HOA & CCR p
I saw that also. Absolutely no information on the site except go to the expert in your area, or sign-up and join. Kip -- Kipton Moravec AE5IB .- . ..... .. -... == Four Way Test Is it the Truth? Is i
I was asked how far from the side of a tower should a omni antenna be to not get too distorted/affected by the metal in the tower. I need a practical answer so Infinity will not work. :) I am certain
So 5' should be enough. Since we are using a WRT54GL we do have diversity so we could put one on each side. The concern at 5 feet is now length of coax (although not as bad as tower screwing SWR). We
Not to hijack the thread or anything, but I have been following this discussion, and the comments suggest drilling holes into the rock base and attaching the rebar into the holes with something like
I would probably put a Software Defined Radio (and computer) at the base of the tower and run Ethernet cable back to the shack. Even with that you will need a switch in the middle as Ethernet has len
