Handheld UHF Radios
Tom Vondrasek | 12 December 2025 | 4 minutes to read
UHF handheld radios are designed to be portable just like a mobile phone. They do everything an in-car mounted unit does and provided they are tuned to the same channel, they can communicate with each other.
Handheld UHFs can look similiar though the pricing can vary greatly. The reason is some are built strong and sturdy for tradies to use, where others are cheap and expendable, so you can give them to the kids to play with. They both still perform the same function, it is up to you to choose what suits your needs the best.
Let's look at UHF handheld radios so you can make a more informed decision:
Handheld vs In-Car UHF
The big difference between an in-car and handheld UHF unit is portability. A handheld can go where you can go and an in-car is limited to where a vehicle can travel. They both have 80 channels and can communicate with one another. I consider them partners and if you own one type, then owning the other can be a good investment. It does still boil down to the reasons of why you want or need it.
Strengths & Weaknesses
Naturally there are strengths and weaknesses to both types:
Range - An in-car unit does have a range advantage as they usually have more transmit power than a handheld device. The antenna is mounted on the exterior of the vehicle and is longer than the short, stubby unit on a handheld which helps increase range. Using a handheld inside the cabin means the antenna is in a metal box which can restrict its range. Handhelds can work better if you step out of the vehicle to use it.
Battery power – A handheld being portable has a battery which only lasts so long before it needs recharging. In-car works the moment the vehicle is turned on.
Portabilty – No contest, the handheld can get anywhere you can. Be aware UHF is a line-of-sight communications medium. The more obstacles between you and the person you are talking too, the harder it gets to communicate.
Costs – Generally 1 x Handheld UHF unit is cheaper than an in-car setup which needs the in-car UHF unit, antenna and vehicle installation. Even if you install it yourself it still takes time. Once you have them, then the handheld running costs like battery life and recharging are ongoing, which an in-car unit does not have.
For Work
The handheld UHF radio is mainly used by tradesman working on large building sites as a way of easily and cheaply communicating with each other. Being small, compact and very robust they can be worn on the body, making them within easy reach. They have the added advantage of being able to listen in to other conversations, so the wearer is kept informed on what is happening at the site.
Most sites have the particular UHF frequency listed at the entrance so you can tune in when you arrive. Groups or companies may use their own separate channel for communications. For example the main site may be channel 12 and the Electricians on-site could be on channel 15.
A Good Work Handheld UHF
The handhelds bought by the trade are normally the more expensive high end units as they want reliability and range. A good example is Oricoms DTX600 which has a powerful, adjustable 1 to 5W transmitter, as well as an IP67 rating making it water and dustproof. Its diecast metal chassis is made to take a hit and keep it functioning. The battery is designed to give approximately 30 hours operating time before a recharge is required.
For Play
If caravaning or off-roading in a group or on your own, an in-car UHF unit is a must have. It helps you stay in touch not just with your own tribe it also lets you communicate with others sharing the same route. Getting information or warnings on weather, traffic, hazards, accidents or camp sites is invaluable.
How does a handheld UHF Radio Help?
A handheld UHF complements the in-car unit in many ways. Used together as a team, it can help with:
Reverse Parking – Having someone at the back or side of a caravan, boat or trailer to help when reversing is gold. Even if their directions are confusing or poor, at a minimum they can let a driver know when to stop before they hit something.
Terrain Taming – When off roading, they can be an extra set of eyes outside the vehicle to help direct a driver through some challenging terrain. Whether it’s a steep hill, big hole, blind corner or water crossing, while the driver has their hands full, the spotter can relay helpful hints to avoid the worst obstacles.
Bush Trekking – When parked up in camp, they can be used when out surveying the local surroundings to stay in touch with base camp or even each other when in a group. Whether looking for firewood, a fishing spot, finding water or strolling through the bush they are a great way to stay in touch for those just in case moments.
Child Minding – When taking the kids and you’re in a caravan park or on a beach or in a paddock they love exploring. You can stay in touch with a handheld UHF. It gives you piece of mind knowing if there are any issues or you simply need them back for a feed, you can contact them. Some companies offer cheap, colourful, multi-pack UHF handheld kits that are ideal for this purpose. Not always available they make a good stocking filler around Xmas time.
A Good Play Handheld UHF
Whether you buy a more expensive handheld UHF radio or a cheap one is up to you and your budget. The higher the price usually means more transmit power, (5 Watt compared to 1 Watt) which gives a greater range or coverage area.
A good all-rounder is Oricoms UHF-2600-1OR in bright orange. Believe me, bright colours are good when you place a UHF unit down in the bush and then try finding it again. It is IP67 water and dustproof so rain or puddles won’t affect it. In fact, if you drop it in a river, it floats and it has light that starts flashing. Great for kayaking or canoeing though you do need to grab it before it floats away.
Its battery lasts approximately 24 hours before it needs a recharge and you can record the last 6 minutes of talk time and play it back if required. It has 2 Watts of transmit power.
In-Car Kits for Handheld UHFs
This accessory turns a handheld unit into an in-car unit. They are a semi-permanent solution and most UHF companies have them. The important point here is these kits are specific to certain handheld radios, they are not generic.
A charging cradle is mounted in the vehicle and used to plug in your handheld UHF radio. It plugs into the cars power so the unit can charge much like a mobile phone.
Your handheld unit has a removable antenna which can be unscrewed. The in-car kit has an antenna cable that screws into this. On the other end of the cable is a magnetic roof mounted antenna. This is placed on the vehicles roof.
The antenna is only left on the roof when using handheld radio. Antenna cable can be put through the window or door jamb of the vehicle, so is easily installed or removed. It helps increase the range of your handheld unit.
A Handheld UHF for All Occasions
Whatever your need, be it work or play a handheld UHF is a cheap reliable way to stay in touch when you are a few kilometres apart. It compliments any in-car UHF solution or can be used with other handheld UHF’s to have their own little party.
