As you probably know, the  famous Art of Electronics, by Paul Horowitz (W1HFA) and Winfield Hill, is the comprehensive go-to bible for hams and other electronics devotees. Published by Cambridge Univ

Not to be outdone, the television industry has responded with its own bad standard, the type F coax "connector," which uses the unsupported inner wire of the coax as the pin of the male plug, and a

In the context of RF, why is that bad? furthermore, the design of the connector is such that both shield and center conductor tend to make poor contact. That depends entirely on the quality of the co

Since the time of Horowitz's first print edition, the F type connector has evolved into a very reliable small-signal RF connector. The mating inner connection has improved into a concentric fit arou

That's because AES Standards define Pin 1 as the designated shield contact, with no connection to the shell. They call for Pin 1 to be bonded to the shielding enclosure at the point of entry to ACTIV

That's something I've never experienced, and I did a LOT of work in downtown Chicago! I suspect something else in that interface is causing the problem. What frequency was the RF? Were all the cables

Couple more thoughts. Many years ago, running Jazz Fest, I had a lot of AKG condensers, including a version of the C414 that had Pin One problems. This was '80, long before that was known. I killed R

I'm using Belden twisted-pair mic cable with Neutrik XLR connectors. The cable shield is braided, no foil. I also tried Canare star-quad cable with no change. Before bonding the shells to Pin 1 at t

Jim, AES Standards, like all REAL Standards, are produced by engineers working in a very broad cross-section of the industries who will use those Standards. Your application is but a pimple on the el

All this is interesting. During my time working at colocated AMs and doing hundreds of remotes on sat trucks, I don't remember having to connect the shells of an xlr to pin 1 to eliminate external pi

The AES standard for not bonding Pin1 to the shell is a good overall strategy. The concern if done in a midline XLR-to-XLR splice is that the uninsulated metallic shell can inadvertently contact anot

Interesting indeed -- I first proposed a concentric capacitance in the course of an AES EMC WG meeting as a solution to the need to break the shield at one end of a cable to prevent excitation of leg
