Is Print Advertising Dead?

The electronics industry embraced the Internet early on. Now, it is reported that 80% of engineers use the Internet to find new information and suppliers. So, the question remains, what is the future of print advertising in an Internet world?

There is still a place for online advertising, but it will not garner the position it once did. There are still places where it is inconvenient to read a computer or I-Pad type device.

Just look at your children or grandchildren and how comfortable they are reading from the computer or some other electronic device. I personally like to have it on paper, but the next generations may not need that crutch. In fact, they may see the printed version as an inconvenience.

Another factor is the information is no longer current. I subscribe to the Wall Street Journal, print and online version. It is interesting to see how much new information in online that when I am reading the print edition that had been delivered within the last half an hour.

The print industry, will not disappear, from the landscape altogether, at least not in the immediate future. It is, however, going to be playing a less significant role than it had in the past. It's role will be inversed in the future with that of it's online cousin. At first, the Internet supported the print media advertising. Now, the print advertising's role will be relegated to supporting that of the online campaigns.

Flexible Microwave Cable

This is a post about one of our Wavetronix products.

There are essentially two different categories of RF/microwave cable. One is semi-rigid coaxial cable and the other is flexible coaxial cable. Coaxial cable has an inner conductor that is surrounded by an outer shield that acts as an insulating layer. Both of these types of cables are used in RF/microwave systems with an impedance of 50 ohms, but they can also be used in broadcast applications with an impedance of 75 ohms.

Obviously, both of these cable operate in the RF to microwave frequency range. The semi-rigid coaxial cable can only be bent one time at least without a significant loss it its usefulness. This is a limiting factor for it's use. The flexible coaxial cable, on the other hand, can be bent more easily than the semi-rigid coaxial cable, and more often, without significantly derating it.

The use of flexible coaxial cable has been on the increase over the last several years, whereas the semi-rigid coaxial cable has, for the most part, been on the decline. The semi-rigid cable still has its uses, such as in satellites and space applications, but the number of these viable applications has been dwindling in recent years.

The flexible cable has replaced many of the semi-rigid coaxial cable applications because of its ease in forming it to a specific shape. Even so, the semi-rigid cable provides superior shielding because it has a solid copper outer sheath whereas the flexible cable has a braided outer conductor.

In both cables signal leakage can create a problem. It can occur from the outside environment inside the cable resulting in noise and signal disruption. This signal leakage can also occur within the cable itself causing RF interference of nearby devices.

Both flexible coaxial cable and semi-rigid coaxial cable have their advantages and disadvantages. Choosing the correct one will depend upon the specific application, but these days the chances are it will be the flexible cable.

What's in a (Conference) Name

I just returned from a trade show and conference in Jacksonville, Florida where we represented two of our Subsidiaries, Tepro (resistors) and Arizona Capacitors (obviously capacitors). The name of this conference is CARTS, which stands for Capacitor and Resistor Technical Symposium. Although I believe it could be renamed CATS, as the capacitors have taken over and there is not much in the way of resistors anymore.

The next show I will be attending is for Res-net Microwave. This show is located in Clearwater Beach, Florida and it's name is WAMICON. This stands for Wireless and Microwave Technology Conference (the word "Technology" must be implied). This sounds better than RF and Microwave Technology Conference (RFAMICON).

I have never been a big proponent of acronyms, but in the case of some of these trade shows, I think it is for the best, especially when a Tweet is limited to 140 characters.
