SMA connectors and PMR 446 Ariels?
Looking to build a remote Bike Comms unit fo rmy motorbike.
I Have a Kenwood 3107 Radio (PMR 446) which has a removable ariel with SMA connectors.
I am looking to connect this to an extension cable / patch cable and terminate it on a panel mount so I can use a compatible ariel
Anyone know if WiFi patch cables can be used ? is it possible to obtain the parts ? anyone in the UK know where from ?
All the sma connectors I have seen use a coax for uhf frequency’s. If you do this, use a SWR meter to tune the ariel length for your radio.

Couplers
Coupler
Couplers are of electronic device that joints two electronic circuits or sockets
In an electronic device there are many types of couplers which are known as acoustic couplers
In telecommunication device known as a directional coupler
A kind of laser mirror known as an output coupler.
A connector between two moving parts to relay the motion, such as a Universal joint or an Oldham coupler
Acoustic couplers: In these types of couplers transmission of digital data is permitted between modem of computer terminal and telephone line in either direction without making direct connections.
Directional coupler:- This types of couplers have four parts in which one is as input ,one is as ‘through port where most of incoming signals exists ,one is considered as coupled port where a fixed fraction of input signals appears mostly in dBs and an isolated port which is usually terminated. If the signal is reversed so that it enters in “through port”, most of it exits the “input” port, but the coupled port is now the port that was previously regarded as the “isolated port”. The coupled port is a function of which port is the incident port.
Output coupler: -An output coupler is a partially reflective mirror which is used in lasers to extract a portion of laser beam from the optical resonator
Oldham coupler:- Through this torque is transferred between two parallel,It has three discs , one coupled to input , one to the output and middle disc is joined to the first two by torque and groove .The Torque and groove on one side is perpendicular to the torque and groove on other .These types of coplers are most compact .
The coupler is named for John Oldham who invented in Ireland in 1820.
Features
1. High Performance
The high frequency characteristics of couplers feature extremely low loss, a high degree of matching, and high isolation.
2. Power Uniform Distribution and 90°Phase Difference Type
In this coupler has one input, two output (or two input, one output) power uniform distribution type having a 90°phase difference between the two outputs (or two inputs).
3. Miniature and Lightweight
Corrosion-resistant aluminum is used in the couplers for the case and some manufacturers has original pattern design of these type of couplers
Which uses a stripline triplate method enables the couplers to be miniature and lightweight?
4. Couplers with SMA Connectors
Use of SMA connectors which feature stainless steel for the exterior
Cladding makes these couplers durable.
5. Equipped with Tabs
Tabs permit direct mounting to surface circuits in the couplers
6. High Power Type
This type of coupler can be used with up to 100 W of power
.
Applications:-
Couplers can be used in mobile phones base stations
Measurement equipment
Radio communication equipment
Couplers as a communication tool can be vital for the public safety and security services in a critical mission”.
Any untrained staff can use these types as these are so simple Antenna couplers
