The SWR meter is then set to REF position, the reading shown on the meter is the amount of reflected power relative to the forward power. To make an SWR reading the transmitter is switched on, the meter is set to FWD position and the CAL control is turned to make the meter needle point to 100%. In the REF position the meter indicates the reflected power traveling on the antenna cable, this is the power that has not been absorbed by the antenna returning back to the transmitter. In the FWD position the meter indicates the forward power traveling on the antenna cable, this is the power going from the transmitter to the antenna. SWR meters have a switch on them usually labeled up as FWD and REF. This connects in line between the transmitter and the antenna and antenna cable. Some of even the cheap meters are usable to 50 MHz, and even usable on 2 Meters, but those are usually the 'bridge' type meters, not those that use a toroid type core, which tops out at about 30 MHz, max. If you have some stuff that not is listed here you can donate this by contact mods.dk. IF you get similar SWR readings both ways, the meter is balanced for that band. Significance of the SWR reading An SWR of 1:1.0 or sometimes just referred to as 1. All serious radio stations should have one of these. In this page you find schematic, users and instructions manuals, service manuals, technical supplement, leaf leads and other good stuff. The SWR meter is then set to REF position, the reading shown on the meter is the amount of reflected power relative to the forward power. At the other end of the scale an SWR of 1:Infinity indicates that no power is being absorbed by the antenna and all the transmitter power is being reflected back to the transmitter.ДЄ useful piece of test equipment that measures SWR is an SWR meter. An SWR of 1:1 indicates that the antenna is perfectly matched and there's no reflected power. The term SWR is used to measure the performance of an antenna.

The antenna is effectively a transformer between the transmitters RF electrical current and free space A well tuned antenna will take all the power put into it and radiated it all into free space. It's a bit like driving a car with flat tyres, it will move slowly, but most of the power will be used in chewing the wheel rims to pieces. Used for Component & Device Equipment Testing, Operation & Performance Rugged & Durable Housing Construction, Cabinet Heatsink Built-in Cooling Fan Power ON / OFF Switch Pyramid Compact Hobby Power Supplies Safe for Tabletop Placement Technical Specs: Amperage: 12.0 AMP (Constant), 14. A poorly tuned antenna and antenna cable will send the power back to the transmitter and in worse case cause it to over heat resulting in permanent damage. A transmitter is only as good as the antenna it is connected to. You can have the biggest and the best FM transmitter in the world, but if the power doesn't get from it to the antenna you may as well turn it off.
