PSA Antenna SMA Wideband Telescopic Antenna w/SMA Connector

This antenna is intended for general purpose applications where absolute measurements of field strength are not required.

The antenna is a high quality unit manufactured by Watson with a knuckle joint hinge and an impedance matching transformer in the base, terminating with an SMA connector suitable for direct connection to the PSA1301T or PSA2701T.

The length is adjustable between 7cm and 34cm. 

The useful bandwidth is specified by Watson as 25MHz to 1.9GHz.

The resonant frequency as a quarter wave mono-pole is adjustable between approximately 220MHz and 1.07GHz.

NOTE:

This antenna is not suitable for making absolute measurements of field strength, however it can be very useful for determining the frequency of RF sources and for making relative measurements of amplitude (e.g. to determine the effect of a modification on the amount of signal radiated at particular frequencies)

For absolute measurement of amplitude at a specific frequency, a calibrated antenna will be needed.

For accurate field strength measurements over a wide frequency range, a set of calibrated field probes will be needed.
