line stretcher or phase shifter - microlab/fxr sr-05N
Line Stretcher or Phase Shifter by MICROLAB/FXR
Operates over a frequency range of 1 MHz to 4,000 MHz - In perfect condition
Microlab/FXR Model SR series of Line Stretchers or Phase Shifters is designed to adjust the electrical separation between components without introducing additional mismatch using a special telescoping section which maintains constant impedance throughout the travel length.
Beryllium copper contacts assure long life and noise free operation. Mechanical end stops at each end of the travel prevent accidental disassembly, and locking caps allow adjustment of sliding tension and provide final adjustment locking.
LINK TO MANUFACTURERS SPEC SHEET
Units are new or like new. Any questions, call Fred Daniel at (***) 640-8899 Pacific 9 AM to 9 PM or email to sale at ptptelecom dot com
Model SR-05N with Type-N connectors and are 50 ohm
Most units are still in manufacturers protective bag. Use these for phase cancellation of interference. If you are not sure how to do it, just ask us. Achieve 15 to 40 dB reduction in interference from on-channel signal, or from broadband noise from an adjacent channel. These will work at any frequency below 4 GHz. At frequencies lower than 500 MHz, you will realize less than 1/2 wavelength in adjustment. Simply add fixed lengths of cable to extend the phase adjustment.
There are other ways to adjust phase, but this is the most stable for long term reliability.
I have photos of the unit, but they do not photograph well.
