What is a coax switch?
What is a coax switch?
A coaxial switch is an electromechanical relay – a passive component – used to direct RF signals from one path to another path. This type of switch is widely used in signal routing applications where high frequency, high power, and great RF performances are required.
Can you shorten a VHF antenna?
Active member. Yes, you can shorten the cable. You shouldn’t make it less than 1m long and the antenna should be no less than 1m from the radio. Otherwise, chop away.
How do you cut antenna whip?
If your antenna needs to be further shortened, you can usually do this by either trimming the stainless steel whip with pliers OR by removing the tuning screw from the tip of the antenna. These options will often allow you to shorten the antenna enough to finish tuning.
What is antenna switch module?
Antenna Switch Modules (ASM) support telecommunication-related features in smartphones and other network-connected wireless devices. Multi-band network-connected wireless devices are supported by these modules.
What does an RF switch do?
A Radio Frequency (RF) switch is a device that routes high-frequency signals through transmission paths. They also support the integration of multiple radios that use a single antenna. The need for RF switch circuits is due to the increasing demand for wireless communications at higher frequencies and wider bandwidths.
Can you cut and splice antenna wire?
Assuming you mean the antenna to radio lead the answer is no. It is a co-axial cable so ‘special’ splices required (radio shack). If you mean the up/down power wires then yes, normal splices work.
Can you cut a VHF antenna wire?
Yes, you can shorten the cable. You shouldn’t make it less than 1m long and the antenna should be no less than 1m from the radio. Otherwise, chop away.
How long should a whip antenna?
For example, the common quarter-wave whip antennas used on FM radios in the USA are approximately 75 cm (2.5 feet) long, which is roughly one-quarter the length of radio waves in the FM radio band, which are 2.78 to 3.41 m (9 to 11 feet) long.
How do I lower the SWR on my antenna?
If your antenna is mounted down low on the vehicle, like on the bumper or behind a pickup truck’s cab, the signal can bounce back to the antenna, causing a high SWR. To alleviate this, keep at least the top 12 inches of the antenna above the roof line, and position the antenna as high as possible on the vehicle.
What does antenna module do?
It is used to convert electric energy into radio waves which enables communication/instruction between two points. Application specific antenna modules are available, such as antenna modules for LTE, GPS and SDARS applications, Array Antenna Modules and others.
What is an RF switch box?
RF switchers were designed to switch between Cable TV, Satellite, Video Games and other home video products with coax cable RF connections. RF switchers feature db Isolation which allows the elimination of interference from external devices and crosstalk between connected devices.
Can you solder antenna cable?
Soldering antenna cables is generally a bad idea. Antennas are very delicate, high frequency signals, and an unshielded blob of solder can completely mess up the properties of your antenna.
What is a shortened vertical antenna?
Shortened vertical antennas have a coil to electrically fill the gap of shorting the radiating element. The first thought was to copy the design of the MFJ antenna with some minor changes but then I decided to go on a different path and design it almost from scratch.
What are the different types of antenna switches?
Antenna Switch, Manual, 2-port, Center Ground Position, UHF Female, SO-239, Each Coax Switch, 4-port, Rated Through 1.3 GHz, N Type, Female, Each Coax Switch, 2-port, Rated Through 1.3 GHz, N Type, Female, Each Antenna Switch, Manual, 4-port, Center Ground Position, UHF Female, SO-239, Each
What is the power rating of the antenna switch?

What is a shorting bar assembly?
Each shorting bar assembly comprises a shorting bar of electrically conductive material which is spring-biased into engagement with each contact of its associated mating pair.
