A waveguide isolator transfers RF signals in only one direction on the waveguide with minimum loss.
This is very useful in cases where a very low input SWR is needed or to reduce reverse direction interfering signals.
All isolators are designed and tested to work seamlessly together with Swedish Microwave LNB and LNA products.
All isolators have high operating temperature range and are waterproof and corrosion resistant for use in outdoor environments.
