Cuming-Lehman Chambers
It’s nearly impossible to perform VHF/UHF measurements in a rectangular chamber. In the 1960’s Emerson determined that tapering one end of an Anechoic Chamber would cause the chamber to act like an indoor ground reflection range.Tapered Chambers work very well at the lower frequencies. Their design forms a uniform illumination across the test region. The tapered end of the chamber forces the wall images close together forming a source antenna array. Tapered Chambers are usually a less expensive option compared to rectangular antenna measurement chambers or compact ranges.

Cuming-Lehman Chambers
Most antenna measurements need to be carried out in the far field; that is, the test antenna should be illuminated by a plane wave. Typically this is carried out by providing sufficient separation between the source and the AUT so the spherical wave approaches a plane-wave character.Near-Field chambers are an excellent alternative to traditional far-field ranges; testing that can be accomplished on a far-field range can be accomplished on a Near-Field test range. This method of testing allows an operator to employ an indoor anechoic test chamber at a reasonable cost and avoid the problems associated with weather and security concerns often encountered when using an outdoor test range.

West Coast Custom Designs, LLC
When the antenna is touched to the tubing wall or electrode wires, the tester will cause the viable tubing to illuminate in a pulsating manor. This pulsing feature is fantastic for testing neon in bright sunlight as it is easier to see the light when flashing.

MegiQ BV
The unbalanced interface of a VNA is not very well suited for measuring balanced circuits like antennas, transmission lines or chip impedances. In fact it is nearly impossible to get a decent calibration on a balanced 2-port measurement using coax cables.
