2 Way Radios from Allen Leigh Security and Communications

Two Way Radios are the most cost effective and fastest way to communicate within an organization of 2 to 200 people. Allen Leigh sells Vertex Standard models from the Yaesu Corporation, some of the highest quality 2-way radio systems on the market. Amateur radio enthusiasts find the Yaesu radio systems to be a very good brand and a leader in 2 Way radio technologies. Yaesu is a Japanese company that uses nothing but the best, from components to the manufacturing processes, and that is why they can offer a THREE YEAR WARRANTY on all their commercial radios.

2 Way Radio Systems

Simplex Radio Systems

Simplex radio systems are very simple. All radios are tuned set or programmed to a particular frequency which is allocated to you by Industry Canada. We initially set your radios up to a temporary frequency so you may use your 2 way radios while Industry Canada finds a frequency for you to use on a permanent basis.

Repeater Radio Systems

With the Repeater Radio system there are two frequencies that your system uses, one frequency for transmitting and one for receiving. . The hand held puts out only 5 Watts of power. With a Repeater system, the base would pick up the transmission then rebroadcast it at the higher power so the little handheld now has the same effective power as the base and your range and penetration is increased. Note that Industry Canada regulates who can use a Repeater and how many users you need before they will issue you pair of channels.

Two Way Radio Bands

There are two common bands available for use in our industry one is VHF and the other is UHF. Each band has other sub bands within them as well. VHF covers a spectrum of frequencies from 136-174 MHZ, while UHF covers 403-470 MHZ. In the VHF and some UHF spectrums the channels are quite full so you may have to share with a neighbor or someone fairly close to you. The radios manufactured within the last 15 years have standard tone coded squelch. This eliminates you from having to listen to the other parties on your frequency unless you lift your microphone off the hook or push the monitor button.

Two Way Radio Power

Most mobiles have a power rating between 25 and 50 watts. In the band of frequencies that we utilize, Industry Canada dictates that you cannot operate one above 30 Watts. And the performance difference between 50 Watt and 25 or 30 Watt radios is negligible. The curvature of the earth plays a large role as well as the height of the antennas and ground elevation. Trees and other obstructions can create a noticeable difference in performance.

Two Way Radio Range

Big factors in the effective range, is the sensitivity of the radios, which antenna is used, and where the antenna is located. The best location for any antenna is as high as possible but still being on a ground plane, like the metal roof of a vehicle. With a metal roof, a High Gain Antenna will give you the best coverage. A fiberglass or plastic roof requires a No Ground Plane Antenna to get the best coverage

Two Way Radio Use

To use the unit, make sure it is ON and lift the microphone off the mic clip and push the mic PTT (Push to Talk) button. All the other units that are ON will hear the message as long as they are within range of the system. Release the PTT to listen to the response. You can then talk to the base station, the other mobiles, or the handheld portables within your system. Everyone is then within the loop of communications and everyone can make better decisions or call for help! Imagine how much time you will be able to save with a system like this no more back tracking, It makes everyone more accessible for more productivity!

You do not have monthly bills like cellular, you don’t have long distance charges either, what you do have is good clear communications for your operation. There is an annual fee for the frequency spectrum from the government it currently is $41.00 per mobile and $106.00 for the base stations. The 1st year is about 20% more but it is prorated.
