The NOODLE ANTENNA
The “noodle” antenna may be adjusted over the frequency
range of 138 MHz to 174 MHz by adjusting the amount of wire
that is folded back along side the end of the antenna. Use
heatshrink tubing to hold the adjusted length.
range of 138 MHz to 174 MHz by adjusting the amount of wire
that is folded back along side the end of the antenna. Use
heatshrink tubing to hold the adjusted length.
The total length may be calculated by the following formula.
Length (inches) = 2950 / (Freq MHz)
Length (inches) = 2950 / (Freq MHz)
Example:
CH1: 150.000
CH2: 151.000
CH3: 152.000
CH1: 150.000
CH2: 151.000
CH3: 152.000
Center of operating frequency
Length (inches) = 2950/151
Total length = 19.5"
Total length = 19.5"
