2 Way Radio Range

Tuesday, April 20th, 2010

You may have seen radios at a discount store or the local sporting goods store that advertise two way radios with a range of 10, 20 or even more miles. This is purely bogus. If bogus sounds too harsh to you…just ask the seller to demonstrate the advertised two way radio range. He will not be able to do it.

Two way radio range is determined by three factors:?1. Frequency?2. Power (wattage)?3. Obstacles
Frequency refers to VHF (very high frequency) or UHF (ultra high frequency). Radios operating in the VHF band travel the furthest but have little penetrating ability. Radios operating in the UHF band do not travel quite as far but have greater ability to penetrate buildings and forests.
Commercial grade hand held two way radios are limited to no more than 5 watts of power. Some radios have as little as a quarter or a half a watt. This is usually expresses as milli watts…250 mWatts or 500 mWatts. The greater the wattage the greater the two way radio range.
Obstacles include any solid object like building and hills or other radio waves or electrical interference.

A good rule of thumb for determining two way radio range is 1 watt of power will provide 1 mile of coverage in an open area. By doubling the wattage the two way radio range is increased by one third. For example a two watt radio should provide about one and a third miles of coverage. A four watt radio should provide about 2 miles of two way radio range.

Two way radio range can be increased with the use of a better antenna, a repeater or more power. Call us and we can help you find the best 2 way radio equipment for your application.

Telephone Greetings

Friday, April 9th, 2010

Here at 2 Way Radio Express we spend a lot of time on the phone. Besides answering the phone we make a bunch of out bound calls everyday. We are forever trying to make the world a better place one 2 way radio at a time.

It amazes us how many businesses don’t know how to answer the phone. For example, “Good morning. This is the Acme Manufacturing Company home of the big whoop. This is Moe speaking. How may I help you.” Too much. I’ve got to say you can help me by shortening your greeting. No one wants to hear all that. It is even worse when we get disconnected and have to call back and listen to it all over again. Mercifully the people that recited the greeting are just as tired of it and say it really fast so no one can understand them anyway. It sounds like “MmmmmHhhhCoCoCoblurdayblue help you.”

Voice mail isn’t any better. Voice mail greetings seem to fall into one of two categories. The first category is the airline greeting. The airline greeting is delivered in the same monotone as that used by a 30,000 plus hour US Air pilot. Think, “Good morning ladies and gentlemen and thank you for calling US Air. I have stepped away from the cockpit or I am temporarily on the radio. Your call is important to me. Please leave a message and I’ll get back to you as soon as possible and thanks again for calling US Air.” Too much.

The second category of voice message is the “have a good day” message. Years ago this voice message concluded with “have a good day.” Then the message’s conclusion morphed into “have a super day.” Variations include, have a fabulous day, have a blessed day, have a wonderful day and on and on. Sometimes combinations are used producing “have a wonderful, blessed day” or a “super fabulous day.” Unfortunately, all these good wishes do little to improve anyone’s day.

I like more direct telephone communications. I just want to call and say, “Wanna buy some 2 way radios?” Then I’d like to hear them say, “Sure. Who wouldn’t. Send us a dozen.” Then I’d say, “Thanks from 2 Way Radio Express. You have made my day.”

Best Wishes,
