How is VHF signal strength measured?

This is a simple and low cost wide band VHF field strength meter. The field strength is measured by converting the radio signal to DC and measuring it. The RF signal will be picked up by the coil and rectified by the diode D1.

How do you test a VHF antenna?

You can also test the antenna by disconnecting it from the radio and seeing how its signal weakens or disappears. Slowly reconnecting just the tip of the coax connector should slowly increase the signal.

How do you measure antenna signal strength?

Turn your antenna signal meter ON, and tune-in the lowest broadcast channel for your area. Slowly rotate your antenna 360 degrees and stop at the highest antenna signal strength (usually indicated by LEDs). Use a compass to read the direction of the highest antenna signal and record the result.

How do I test my antenna with a multimeter?

Touch one end of the multimeter to the metal jacket around the antenna connector and touch another end to the ground, if the reading is not in zero, then the antenna is not grounded properly. The above-mentioned process is used to check the signal and test an antenna and its connection to television and its reception.

How do you use aerial signal strength meter?

How to Use an OTA Signal Meter

1. The first step is to plug the cable coming from the antenna into the input labeled antenna on the meter.
2. Then plug the television into the meter labeled receiver.
3. Turn on the meter and rotate the adjustment dial fully clockwise.
4. Position the antenna until most of the LEDs are lit.

What is the resistance of a VHF antenna?

VHF antenna is vertical antenna with the length of approximately 1 m. VHF antenna is placed on a position as high as possible. The connection between the VHF radio and VHF antenna is made by coaxial cable. This coaxial cable will have an impedance (resistance for alternating current AC) of 50 Ω (Ohm).
