Understanding SWR by Example
www.arrl.orgFrom November 2006 QST © ARRL sometimes seems that one ofIt the most mysterious creatures in the world of Amateur Radio is standing wave ratio (SWR).
KENWOOD
www.kenwood.comtem which shows a standing wave ratio of less than 1.5 : 1 when using 50 ohm coaxial transmission liner or a system that results in a transmission line input impedance that is essentially resistive, and between 20 and 1 50 ohms will take power from the transceiver through the AT-940. If open wire or balanced type transmission line is used with
AA-2000 ZOOM RigExpert
www.rigexpert.comThe analyzer is designed for measuring SWR (standing wave ratio), return loss, cable loss, as well as other parameters of cable and antenna systems in the range of 100 kHz to 2000 MHz. A built-in ZOOM capability makes graphical measurements especially effective. An integrated Time Domain Reflectometer
Antenna Impedance Matching – Simplified
abracon.comStanding wave ratio (SWR) is a measure that defines how well the antenna impedance is matched to the connected Tx line impedance. A value less than 1.5 is desirable. A low flat SWR enables maximum power transfer from the ... When a series inductor is connected to the antenna, the combined impedance of the antenna ...

www.macoantennas.netADJUSTING THE STANDING WAVE RATIO (SWR) Refer to Figure 4. The dimensions given are approximate and should be used as a starting point.* The gamma match has 2 adjustments. First is the capacitor adjust and second is the slider adjust. Connect a SWR bridge coax between your transmitter and the antenna and check the SWR.If adjustment is required,
