Are UHF and VHF connectors the same?
The UHF connector is a name for a threaded RF connector. The design was named during an era when “UHF” meant frequencies over 30 MHz. Today, Ultra high frequency (UHF) instead refers to frequencies between 300 MHz and 3 GHz and the range of frequencies formerly known as UHF is now called “VHF”.
Can you extend UHF cable?
Yota said: You can shorten the cable without any adverse affects, but just make sure you leave a little length in case you have to resolder a coax connector.
Can you join UHF cable?
If you must have a join put it under the bonnet and wrap it in fresh self amalgamating tape EVERY time it is removed/reconnected. the best method is to run a new cable from the radio to the antenna base and when the antenna is removed put the cable in waterproof bag under the bonnet.
Can you splice a CB coax cable?
No, you cannot splice it. You either have to connectorize each end and use a barrel connector or replace the entire run of coax.
What is the difference between so 239 and PL 259?
Typically, the SO-239 (UHF Female/UHF Jack) is installed ON THE RADIO, and the PL-259 (UHF Male/UHF Plug) is installed ON THE CABLE. The two “mate” and are collectively known as a UHF Connection.
Can UHF talk to VHF?
However, because UHF radios and VHF radios can’t communicate with one another, it’s important to take their differences into consideration when making a purchase. If you already have radios and are looking to add units to your set, be sure to select the same band so that they can work with one another.
Will UHF antenna pick up VHF?
It’s designed to pick up UHF signals at astounding distances, and it does. But, if you read the fine print we also tell you that it will pick up VHF signals at fairly close range. In fact a coat hanger or even a potato can pick up VHF channels from 25 miles away.
Will a VHF antenna work for UHF?
Because of today’s preponderance of UHF stations, there aren’t many different types of VHF-only antennas. Most antennas these days have some combination of long dipoles, as well as short dipoles or loops. Combined together, these are designed to capture both VHF and UHF.
Can you cut and rejoin UHF antenna cable?
you can’t just cut the coax from the plug and rejoin it, the coax center core is solered to the plug, and the collar crimped over the coax to hold it in place, once cut, the plug is a throw away job and about $40 to buy a new plug which comes complete with new coax.
What can I do with excess UHF antenna cable?
Your best option for handling excess coax is to serpentine the cable into a 12 to 18 inch yarn-like skein. Secure the skein in the center with a wire tie and tuck it away. This guy talks about eliminating comman mode current by using a choke (coiled up section of coax) at the antenna. scroll down a little.
Does CB coax length matter?
The coaxial cable running from your radio to the antenna is VERY important. Everything you transmit and receive must travel along it’s length. All too often, the coax is ignored and performance suffers because of the lack of attention it receives. We recommend 18 feet of coax even if you don’t need that much.
Can you twist coaxial cable together?
Electrically, twisting the conductors together is fine. Twisted connections like this would barely introduce a few ohms resistance if that, particularly if done well. Electricity would flow along the cable without a real issue.
What does PL 259 connect to?
The PL-259 is also known as a UHF connector with the common male/female variants. The male UHF PL259 is the most common connector used to interconnect equipment and antennas in ham shacks.
How do you solder a so 239 connector?
At least at HF, all you really need to do is solder the inner coax conductor to the center pin of the SO-239, and use a solder lug to solder onto the braid, and mount the solder lug under one of the mounting nuts. Just unravel the braid and twist ALL the braid wires together, and solder to the lug.
How much power can a BNC connector handle?
BNC connectors are generally rated for use in the DC – 4 GHz frequency range; however, they are rarely used above 500 MHz. While they are capable of handling 80 – 100 Watts average power up to 1 GHz, they typically do not have a maximum power rating. They do however carry a maximum voltage rating of about 500 V.
What is an F-type connector?
A. F. A two-wire (signal and ground) coaxial cable connector used to connect antennas and set-top boxes to TVs, VCRs and DVDs. F connector cables typically carry analog NTSC TV signals, and the plug’s socket is easily identified by its threads. Plugs come threaded and unthreaded, both of which fit the threaded socket.
What is a coax connector?
Coaxial cable connectors are used to connect cables to other devices and are specifically designed to maintain the shielding on the cable. High-quality connectors offer reliable, long-lasting connections. There are two distinct connector styles; male and female.
Do police use VHF or UHF?
Police radios operate in a 700/800 MHz UHF band.
How far can 400 MHz reach?
Thus the typical ranges with around 400 MHz frequency range with 1 W transmitter power are up to ~30 kilometers and up to ~80 kilometers with 10 W transmitter power.
Are walkie talkies VHF radios?
UHF and VHF are the two most commonly used frequency ranges for walkie talkies. VHF features 130-174 megahertz, while UHF features 400-520-megahertz. These higher frequencies can travel in straight lines that are called line of sight signals, unlike frequencies that are below two megahertz.
