The effective height of the ferrite antenna (secondary side) for a signal at the receiver input: (6) hwFA2 = 2 * pi * ยตw * w2 * A * Q / lambda For example: A receiver FPE80 has approximate values: ยตw= 45, Q= 65, dL= 12mm, w2= 3 The antenna designer said that this antenna covers 100 kHz to 30 MHz which is just 100 kHz to 519 kHz more like what the Satellit 750 covers . With a 365pF air-spaced variable capacitor in parallel with around 60 turns and with the 50 ohm point The ferrite bead between the 4 -pin cable shield and PHY ground may be valued between 10 and 50 Ohms at 100 MHz .
A novel, very low-profile wideband antenna operating from 30 to 300 MHz is presented
A lot of modern op-amps such as the 5532 have a gain bandwidth figure of about 10 MHz so 60 KHz is not a problem The following is an email message sent out to the PSN-L mailing list regarding WWVB receivers . The volume control uses a fixed 450-kHz oscillator connected to an LC circuit, part of which is the volume antenna The receiver patch antennas have a combined antenna gain of โ10 dBi while each transmitter antenna has a gain of โ6 dBi .
The Si473x-D60 digital CMOS AM/FM radio receiver IC integrates the complete broadcast tuner and receiver For good performance in MW (LW) band should be user a standard ferrite stick antenna with 12cm x 1cm
Although designed for 530 to 1600 KHz, the UZ-8DX can easily be adjusted to operate on 160 meters as an amplified receiving antenna The effective height of the ferrite antenna becomes hwFA2= 0 . Using a telescopic antenna indoors is nearly impossible these days The CDX1-1745 is capable of delivering stunningly clear, hi-fi quality output, but at the explosive sound reinforcement levels demanded of pro .
That predicted value, though, ignored the permeability of the core
AC adapter, 110/120/220/240 VAC 50/60 Hz AC adapter, 120 VAC, 60 Hz (Canada) AC adapter, 110/220 VAC 50/60 Hz (Europe) LW/MW/SW wide range antenna VHF antenna Rechargeable battery pack Car battery cord Car battery cord Car battery cord Battery case Connecting cord Connecting cord 250 watt transmitters were lined up at the site and up to 8-way hybrid-ferrite combiners were used to end up with 21 or 22 watts per channel to the antenna . It's better heads and shoulders than any ferrite antenna I ever made Getting that antenna outdoors and away from the house is a must .
NanoVNA Vector Network Antenna Shortwave Analyzer 50Khz~900Mhz TFT 70/60/50dB 25ohm, And The Rest Circuit Has Negligible Resista . The final winding will be either 40/44 or 60/44, both on order Using this circuit alone I was able to detect the DCF77 signal with about 1 mV amplitude - I am about 80km away from the transmitter which is near Frankfurt .
