Sorry, but you’ve been had. Although many manufacturers boast that their radios can reach amazing distances, this is, in almost every instance we’ve encountered, a fallacy.

How is this legal, you may ask?

Essentially, your radio quite probably could work over a range of 25 miles, but that is a theoretical estimate, working on the assumption that the myriad variables that affect two-way radio signal (such as atmospheric conditions, topography, objects in the way and etc) are simply not in effect.

All of them. At the exact same time.

So, assuming that you used your two-way radio in a vacuum, where weather didn’t exist and no obstacles, man-made or otherwise, were present, you would be able to communicate with someone else who was further away in that impossible vacuum, maybe even 25 miles away, but otherwise? Forget it.

The fact is that the average two-way radio has a range of between one and two miles and not much more (maybe three, but we’re not making any promises). CB radio fares significantly better, largely because it makes use of large aerials. Now, Signal-boosting equipment can be used to improve your two-way’s performance (for example, repeaters), but such equipment is expensive and hard to obtain for legal reasons.

There are, however, a few factors that can have an affect on your radio’s range. The frequency being used, the power output, the size of the antenna, the complexity of the signal being sent, signal interference, background noise and (as we wrote earlier) objects in the way are all factors that can improve (or hamper) your efforts to get your signal to reach as far as possible.

So, talking on your radio whilst in the car will have a deleterious affect on your signal, as will deliberately walking through wooded areas or places with a lot of rocks/mountains if you can take an easier path.

However, a larger antenna (if you’re tech orientated, the antenna can be replaced with a better one – although this should only be attempted if you are

  1. a) Sure about licensing laws

And

  1. b) Tech savvy enough to void the warranty and not regret it later, can really add a few hundred meters to a radio’s range, as can a switch in frequencies.

Also, your choice of VHF or UHF radio will have an affect as well, a UHF signal, for example, generally penetrates buildings and objects better than a VHF signal, whereas VHF is better for outdoor use where there is a lot of open space to transmit across.

Having said/written that, even in optimum conditions, you are extremely unlikely to transmit over a distance of 25 miles. Sorry.

As an aside, mobile phones don’t suffer from this lack of coverage, largely because cell towers are in place that bounce the signal from one to the other and thus carry it across a far larger area, your mobile is still your best bet to break that 25 mile mark, we’re afraid.

Hope that helps.

If you are looking for a security earpiece with a mic, then you will need to know the varieties available out there. While some types are more expensive than others, what ultimately matters is the quality and durability of what you get at the end. Below is a look at what you get out there:

One wire kit

With this one, there is only a single wire, which emerges from the radio, runs through the PTT and then ends where the earpiece starts. This makes for a simple yet effective look. As for the length of the cable, the one wire kit has a piece that runs between 28 and 34 inches. This means that you have at your disposal a length sufficient to cover the distance between your ears and the waist without any kind of stretching or straining. Of course, the reach of every security earpiece will be determined by the height of the person wearing it. The one wire kit is great for an average height and will work for anyone 6 feet and below.

Most one wire kits come in the original D and G shapes. There are some fancier designs out there as well if that’s what you are looking for.

Two wire kits

As the name suggests, there are two wires involved in this scenario. One runs to the Push to Talk (PTT) button. The other runs up to the earpiece, making for a good looking dual connection. For the purposes of discretion, you are allowed to wear this cable partially disguised within your clothing. One wire will emerge from the radio, rising up your back to the ear in a way that keeps you comfortable. The other cable runs from the radio, up the length of your hands and terminates at the cuffs if you are wearing a long-sleeved shirt or sweater. In terms of length, the two-wire kit is essentially the same as its one wire counterpart, with a reach of 30 to 34 inches. This accounts strictly for the length of each individual wire, and allows the unit to comfortably cover the areas between your waist and the ears. Two wire kits commonly come in the form of an acoustic tube that many who know a little about surveillance will be able to understand.

3 Wire kits

Here, you have three wires coming off the radio. The first wire will terminate where the earpiece is built. The second will end where the Push to Talk button is located. The last will end at a connection with the mic. As with the two wire kits, this one is worn under ordinary clothing, with a cable for the mic, earpiece and PTT button. There is really no standard length for all the three wires and there is no guarantee that all of them will be equal in length, but there is a sense of flexibility in the way you get to use the piece. Always try on sample pieces before making a purchase at a store. Over the internet purchases are trickier but then the measurements will be highlighted long before you order.

Understanding the functionality of PTT technology

Push to Talk is a cutting-edge technology that allows for direct communication between parties at agreed-upon frequencies and distances. The greatest thing about PTT is that it switches communications from duplex to half duplex. This means people do not talk over each other but get to alternate between speaking and listening. PTT is able to loop in two or more speakers at an instance of communication, allowing for conference-like types of engagements between participants. This streamlines communication. Most enterprises prefer this approach to communication because there are no limitations in terms of allotted minutes. As such, there is absolutely no need to stay within the confines of a data plan, which would be both expensive, inconvenient and rigid.

There is no such thing as a right security earpiece. What works for you may not work for all other parties across the board. While your budget matters a lot, you are looking for something that works optimally and stands the test of time. The three types mentioned above are alright if you are looking for something that works all the time. Remember, prices will vary across brands and models.
