Jan 21, 2013 · Without a loop, the alternative is a capacitive antenna (AM car radio antennas are of this type). That's probably what the watches use, with the human as the reference. I'm guessing a lot of signal averaging is used to extract the signal from the noise. A wire (and the shorter the better) from a buried cold water pipe serves superbly for all wire antennas. Loop antennas will not require the ground lug to earth connection as the signal appears across the loop and the circuit is completed at the receiver. Back to the main subject: There are basically three types of antenna available to you.

Palomar Engineers Inductance Turns Calculator (Ferrite) Inductance [mH] Core Size a local mediumwave broadcaster as picked up by a random wire antenna. Thus, some sort of tuned antenna is best for all but the most isolated, rural locations. The most popular antenna for mediumwave DX today is called a `loop' antenna, and can be either of two types: ferrite rod or air-core wound wire loop.

The new designed, fine tuned 60kHz antenna replaces the old 100mm long antenna, and guarantees even better reception than the old model. This module can be used to receive the atomic clock signal transmitted by: - WWVB (US/Canada) - JJY60 (Japan) - MSF (England).

Particularly useful for use with a medium wave loop and a standard table or portable radio as most of them don't have external antenna jacks and rely solely on there internal loop stick. The ferrite rod I used is 5.5x.375 inches taken out of an old radio. Size of the rod is not very critical here nor is type of ferrite material.

Small-size ferrite-core loop antennas. It is often useful to consider the smallest practical size of loop antenna that can be used, say for reception of signals such as those from WWVB at 60 kHz. Using a ferrite core increases the effective permeability of the core and, as you can see from equation 1, that increases the effective length.

Small Loop Antennas. The small loop antenna is a closed loop as shown in Figure 1. These antennas have low radiation resistance and high reactance, so that their impedance is difficult to match to a transmitter. As a result, these antennas are most often used as receive antennas, where impedance mismatch loss can be tolerated.

Using the Small Loop Antenna Joseph J. Carr Small loop antennas have an overall wire length ≤ 0.15 λ. They exhibit deep nulls perpendicular to the plane of the loop, and broad maxima off the ends of the loop. The pattern of these small loop antennas is a variant of the classic "Figure-8" pattern. Although

Full-Wave Loop Antenna Length Calculator. Full-wave loop antennas can be large at lower frequencies, but they are quieter than dipoles and have more gain broadside to the plane of the loop. A circular loop is ideal, but squares, triangles, and other shapes can work well; just make the area enclosed by the loop as big as you can.

The Gurkha's domestic radio using an internal ferrite antenna had difficulty receiving the broadcast because it was further away. The reception was improved by placing the loop antenna close to the radio as shown in the later photograph and tuning it to 1134KHz.. – No electrical connections were required between the antenna and radio.

I"m trying to build a clock that uses the WWVB signal to keep its own time. I have everything built and working except the Antenna portion. I have a 1.1mH ferrite rod Antenna.

  • The WWVB 60 kHz Low Noise Ferrite Loop Antenna is 24 " long and housed inside of the white weatherproof PVC pipe. Coaxial cable losses are so minute at 60 KHz, that the preamp if needed can be located inside away from the elements, close to the power supply, with easy access
  • This particular antenna’s trick, thanks to the sizable ferrite, is the ability to transmit. Granted it is only capable of handling about 20 watts, for a portable QRP rig it is pretty great. Especially with digital modes. Not to mention, that like a normal air core magnetic loop, it has great e-field noise rejection for urban environments.

Directivity is much better than what I have at home on the K9AY.”! eham.net SAL-20 Review by N1DG “The antenna performs just exactly as the RDF suggests it will. The F/B will vary, and seems to be anywhere from 15db to 30db, depending on the arrival angle of the signal.

  • The AW02-60 is a weatherproof and temperature resistant 60 kHz antenna for outdoor use. It includes a ferrite rod with impregnated winding and RF amplifier circuit in a plastic housing, with power provided by the receiver via the antenna cable. The AW02-60 antenna can be placed up to 300m (1000 ) from the receiver using standard RG58 cable.
  • 2 Model of the ferrite antenna The basis of the ferrite antenna is a ferrite core in the form of a solid rod or set of rings. Taking into account the frequency range used, the ferrite material must meet the broadband requirements. It also should have low losses. Therefore, on the basis of the minimum loss requirement in the speci ed frequency ...
  • I wanted to make a loop antenna for receiving WWVB based on the Amidon R33-050-0750 Ferrite rod. This uses the type 33 material and is 1/2" diameter by 7.5" long. After trying a number of different windings I think the current version may be optimum for WWVB at 60 kHz.
