Why would you ever need two different impedances available in the same antenna? 75 ohm is used in television and that is about it. Any impedance issues due to phasing can be overcome with proper coaxial cable lines.

A twenty year old dead thread.

Anybody have any plans for viewing the eclipse on Monday? Are you even in or near the path of totality? I said WTF and took Monday and Tuesday off and will be headed to somewhere along the north shore of New Brunswick Monday morning to be dead centre of the path of totality. It's about 3 to 4...

I agree with above. This has nothing to do with the radios you mentioned. It is all about cell jammers and wifi jammers that have seemed to sprung up everywhere illegally.

Any of them will work, including homemade cable assemblies. Been there, done that.

Although it has been many years since I have been on 11m I remember the heyday of the late 70's and 80's when every man and his dog had a radio. I have never used any more than 100 watts on 11m at any time and for many years was confined to just 25 watts. I did ALWAYS use SSB and had a Wilson...

I wouldn't touch it again. My personal feelings mind you but stuff like this can lead to a blemish on your reputation. Nom telling if he does the same stunt again what he might say about the cause.

Why use wires to communicate via a wireless system? It WILL radiate so it will NOT be private. If you want privacy and a closed system use old telephones with the carbon mikes, a battery of some voltage 12-48volts and you have private comms.

I must admit that any time I hear someone say that coiling up coax forms an inductor, I assume they are talking about the inner conductor, mainly because they usually are talking about that. Lots of folks think that coiling it up will somehow reduce the power output because the cable forms an...

That would be due to common mode problems where a less than ideal ground plane is present and RF is flowing on the OUTSIDE of the cable where it is not supposed to be.

Wrong. The turns are shielded from each other and it does not act like an inductor. Only the outer shield is not shielded from each turn next too it and it will form an inductor aka choke to prevent common mode currents on the OUTSIDE of the cable. It has ZERO affect to the inner conductor.

Holy crap Jeff. We had about 18-24 inches total so far this winter. When we left for Jamaica a week ago we had about 12 inches on the ground. The week we were away we had record temps and heavy rainfall at home. We got home last night and there is no snow left. NOTHING except a little bit left...

No difference now than in 2015 when we were first down. In fact we were here in 2018 during the state of emergency when the government had a major crack down on gang violence. Police and JDF troops everywhere. Tour busses were waved through checkpoints while local transit and private vehicles...

Like the title says. Decided to say to hell with the cold. It has been far to long since we have been away. Currently sitting by the pool in Ocho Rio's Jamaica. Got here about suppertime Monday. It's a bit cooler here today than yesterday. Barely making 81 degrees. Not sure we will survive.

I highly doubt the two flares caused any outages to the cellular network. They were X-1.7 and X-1.8 level and although quite strong, were nowhere near the class X-20+ level we had a number of years ago that occurred without any major problems. It was rated as a 20+ because the true level was...

OK that is not the image I saw on the other site I am on. I checked it again and the other tower I was thinking of was not stolen. It had its guy wires cut and it fell. THAT is the one we were talking about being a case of fraud. Sorry about that.

Keep an eye on the news. Pretty sure this is a case of fraud. One site I frequent made up of current/former broadcast techs and engineers has been discussing this and one mentioned it was a potential fraud/insurance scam.

Cannot view it. Says it is not shared.
