Hi Vic, Well I guess "strong" or "weak" are subjective terms, and not describing what the problem really is. Let's be serious here, the wire isn't a major part of the cost of the antenna. Why not use

I for one would like to see MFJ improve customer service, and spend more money on QC even if the price of gear goes up. I think people would pay a little more for better service and better QC. I thin

There are some clamps that can be used to join two sections of guylines, but they are special and not commonly used. Look at utility wores, and you might see a few examples of these clamps. Some are

It's probably worth mentioning that I wound up with N0AH's RCS-4's. Both of those RCS-4's worked here, although one did have a charred 100 volt disc capacitor across the 12 volt power supply bypass l

They have ALWAYS used molded ABS covers. They use the same connectors, except there was a bad batch of connectors a few years ago. Then you almost certainly have loose connections or moisture in the

Someone else a few months back had a problem with noise using an RCS-4. I told him that virtually every case was caused by defective coax, or water in fittings. His turned out to be a bad feed cable,

That was probably from the batch of bad connectors. A vendor changed the parts without letting anyone know. They were not "cheaper", they were the same price. Sometimes stuff like that happens. It i

There is conflicting information because the design is a "loose" design. Choke baluns work with a broad range of configurations, they are not critical devices. I prefer a single-layer solenoid and s

Hi Steve, The biggest disappointment I have ever had was buying the largest three element Telrex forty meter antenna. Mine was an early antenna, not a later one. It had thin aluminum elements that b

The coax should always be grounded at the top of the tower when a balun is used. That insures the cable shield is at tower potential for both lightning and RF. I had a bad case of TVI once because a

Actually the parallel impedance increases above the self-resonant frequency. The only reduction in impedance occurs at frequencies more than 1.4 times the resonant frequency. If you have a choke of

Transmission line baluns are poor baluns for most applications. They are much more impedance and load critical than choke baluns, more lossy, and don't do as good a job. They are more difficult to m

Pardon the lecture that follows, but I think you have been misled. This really is worth getting into! A 3:1 SWR does NOT cause a 25% power loss. It might cause an increase in loss, but that increase

Woops, let me correct this: That should be "have HIGH loss"...not "be lossless". The rest was OK. 73, Tom W8JI W8JI@contesting.com List Sponsor: Are you thinking about installing a tower this summer?

The best idea is to bury the drop, and get it out of your way. If the wire is a triplex 240 volt line, there are no code restrictions (at least not in this area) other than not having things in dire

First, I assume we would always call the local utility company and ask them if the lines are service drops if we don't know how to identify them. That rule includes extension cords, and the cords on

I asked that question, but no one seemed to know. Locally, there are no codes at all except you have to be 15 feet clear of primary lines. Personal opinions aside, what are the local codes? 73, Tom

I agree with the conclusions but it is important to remember a few things. The actual mismatch normalized to a 50 ohm system ranges from 1:1 to 2:1 at the transmitter. The transmission line sees a 1.
