Just purchased a bundle of UHF5500 with the ANU1200, recommended by one of your state managers.
My question is, is this an overkill or non-practical?
Hi there, thanks for the message. Glad to hear you have got your hands on some great Oricom products, and depending on the application, this is by no means an overkill. Some people prefer the handheld radios whereas others might go for a fixed mount radio. It really depends on where you are going and personal preference and the type of terrain you are travelling in. All the best, Oricom.
I bought two and on one it is stuck displaying -80 and continuously displays menu options flashing on LCD. It will not transmit or receive even on ch 80. Is there a way I can fix this or is the unit faulty?
Hi there, thanks for the message. Sorry to hear of the issue you are currently experiencing with your UHF5500, and for this one, we recommend checking that no buttons are stuck down, and try a reset. To reset, press and hold Monitor and power on. “Reset” will appear in the display and the radio will then return to standby mode. If you continue to have an issue with your UHF5500 and believe the unit to be faulty, please call our dedicated Customer Support Team on 1300 889 785 Mon-Fri 8am-6pm AEST, as they will be able to assist in working with you towards a solution. All the best, Oricom.
Could this be used for hilly forest terrain with sometimes no line of sight ?
Hi Ariel, thanks for the message. For this one, UHF CB handhelds work on line of sight because of the smaller size of the antenna. We would not recommend using the product in a hilly/forest terrain where there is minimal line of sight as you will experience issues communicating effectively, as smaller handhelds wont be efficient in this terrain. Thanks and all the best, Oricom.
G'day. What range can I expect for reliable line of sight communication between the two hand held units? Regards
The range of a UHF CB radio is: ‘The combined line of sight of both stations (antennas of the units)’
UHF radio signals travel in straight lines between the radios, anything between will attenuate the signals and in some case stop them altogether. In some cases, where changes are experienced in previously “good range”, this could be attributed to environmental changes around your immediate area such as vegetation growth or new buildings.
The range is more of a question of what is between the stations. The attenuation of the signal in free air is very low, as moisture is added the attenuation becomes greater. Trees and other types of vegetation also contain water so a signal through a plantation or forest of trees will also be attenuated to some degree if not completely lost.
Elevation improves the line of sight to the horizon it is also good if you are on the road and trying to communicate with another station a few vehicles in front of you, it may not be possible to talk between two handhelds but once you put an antenna outside and higher than the roof of the car communications might be possible, just a little elevation can make a big difference.
If there is nothing between you and the other station the limiting factor is the horizon at about 1.5m above ground level and looking at the same point on the horizon the best range possible would be approximately 10km (5km for each station)
Receive sensitivity is as important as RF power for range if there is a lot of RF noise or other transmitters close to the receiver it could be desensitised by these stronger signals and give the impression of poor range or poor receiver sensitivity.

Hi Oricom Official, what is the standard range (kms) this model can handle? Other models state 10 KMs, others are closer. What about the UHF5500-2?
In summary: the range of UHF CB radio signal, is line of sight and this is limited by the horizon. More power (i.e 5 watt over a 2 watt or 1 watt) will give you a greater penetration in scrubby terrain.

The range is more of a question of what is between the stations. The attenuation of the signal in free air is very low, as moisture is added the attenuation becomes greater (anyone with satellite TV would have seen rain fade). Trees and other types of vegetation also contain water so a signal through a plantation or forest of trees will also be attenuated to some degree if not completely lost.
Will a 5 watt unit may have greater range than a unit with a lower transmit power?
Yes, it will, provided the other station is able transmit with the same levels. With more power the signal will go further, not so much in open area distance but through objects or rain i.e. better penetration in built up areas or through vegetation.
It is the same when in a built up area the signal may not go through some buildings and will not go through a hill there as some exceptions, a signal can bounce off a building and give the impression that it is working fine sometimes atmospheric conditions can also affect the range or signal propagation.

is it splash proof?
Does the car charger supplied with these units plug into the bottom of the radio or does the car charger plug into a cradle that the radio has to sit in?
Hi Rick, These units come with a charging cradle. See full details on our website: http://www.oricom.com.au/uhf5500-2-handheld-cb-radio.html or, if you have further questions, please feel free to contact our Customer Support Team on 1300 889 785. Cheers, Oricom UHF CB Radios.
