RF direction finders use antennas to receive radio frequency signals from a transmitter. By comparing signal strength or phase differences at multiple antenna locations, the direction to the transmitter can be determined. This information helps locate the source of a radio signal.
A configuration on a map that acts as a direction finder is known as a compass rose. A compass rose is also known as a windrose.
An instrument that measures, electronically, the direction of arrival, intensity, and rate of occurrence of atmospherics; a type of radio direction finder, it is most commonly used to detect and locate cloud-to-ground lightning discharges from distant thunderstorms.
Rf is about .45
RF Generation was created in 2004.
RF Online happened in 2005.

Finder works just like the Start button on a Windows PC.

you have to have a item finder and then use it and it will turn you towards the direction itis and its in front of the trees

AN RF Isolator is really a three port device called an "RF Circulator" in which one port is always terminated correctly with a suitable load. RF Isolator are usually passive and are bandwidth limited.Typical use: It used in the output of a RF Transmitters High Power Amplifiers but before a BP/ HP filter and the antenna.Typical Function: To isolate a TX RF Power Amplifier output from receiving RF feedback from external sources. i.e. In this case the RF coupled in from other Antenna systems in close proximity. Such undesired RF feedback would cause intermodulation / harmonics products to be generated within the RF amplifier and consequently be re-radiated out along the the desired RF signal to the antenna and possibly cause interference. Often used on all TX's in two way radios sites to avoid local IM.SIMPLIFIED: In other words an Isolator passes RF in one direction but attenuates RF in the other direction.Note: The RF Isolator is slightly non linear and therefore it can cause low levels of intermodulation / harmonics. So it is good practice to place either a basic Band Pass or High pass filter after the RF Isolator to attenuate the unwanted IM products.Tuning these RF Circulators / Isolators correctly requires a suitable network analyzer or combination of RF Bridge / Spectrum Analyzer with Tracking generator.

A stud finder works on plaster walls by detecting changes in density behind the wall. When the finder passes over a stud, it senses the denser material and alerts the user with a signal or light. This helps locate the studs for hanging heavy objects or mounting shelves securely.
