Accurate Antenna Systems Mean Maximized Results

Posted by Jill McNamara on Wednesday, December 7, 2011

Tom's Tech Talk (#11): Antenna Systems

 I can’t tell you how many times we run across systems improperly designed based on their licensing requirements. Each FCC licensee is required to meet both height and power requirements for all of their fixed base station equipment that is indicated on their license.

      Many times people take the approach that to reach their people in the field they need to increase the gain of their antenna’s and the power on their base stations. What they don’t realize is that they may become an interferer with an adjacent co-channel user and  are therefore  subjected to a fine by the FCC for exceeding their licensed effective radiated power. We had one instance where the combined antenna gain and power from their equipment was enough to reach Madison Wisconsin from the Western Suburbs of Chicago.

Narrowbanding: Time is Running Out!

Posted by Jill McNamara on Friday, November 11, 2011
   Don't have the time or interest to read through 5 or 10 pages of Public Notice procedural data about Narrowbanding? We're going to make it simple for you by cutting out what's somewhat important and highlighting what's most important! Here's what you need to know to make sure your radios operate after January 1, 2013:
  1. Who does it apply to? The mandate applies to all VHF and UHF Public Safety and Industrial/Business licenseees using land mobile radio (LMR) systems. For those of you who have licenses with the Federal Communications Commission (FCC) and are operating in frequency bands below 512 MHz, you will be required to replace or reprogram your entire radio system.
  2. Planning is key. Narrowbanding of your existing radio frequency is fast approaching! With the interface we have had with existing customers, the logistics takes a long time. In addition, purchasing of equipment and getting the programming lists correct is key!! I must urge you to not hesitate in putting a narrowband implementation strategy together. The longer you wait the longer everyone waits and the process may not be completed by the last day of 2012.
