The electrically small size of these loop antennas has the advantage of convenience in handling, availability of a zero- response orientation, and a simple expression for the voltage produced by a given field...Dec 01, 2019 · So I spent my antenna time working indoors preparing the next 40 radials. These I cut to 15′ in length each, crimped the loop connector, and then coiled the radial carefully so they wouldn’t become tangled. The following weekend I as able to quickly install these radials much more quickly than the first 20.
The loop-on-ground makes an excellent companion to a vertical, using the LoG as a dedicated recieve antenna and the vertical as a dedicated transmit antenna. The vertical can be installed in a back yard away from view, while the LoG can be installed in a front or side yard, where it will be completely invisible, safe, and well-separated from the transmit antenna.

It includes a very high dynamic range low-noise preamplifier that can be mounted to a pole or any flat surface. Turn your radio on, select 'AM' and set it near the coil. You may have to twist and turn the radio, and move it closer or farther away, but stations that were weak and scratchy will leap out at you. The first time I made one of these antenna systems, I added a small switch in series with the ground connection. INSTALLATION INSTRUCTIONS The FISHER Model 80-T is supplied with the following : ntenna Plug I—AM Loop Antenna with plug attached I—FM Folded Dipole with plug attached Mounting screws and flat washers I—Shielded Cable Jumper Cables, installed 2— Moun ting Templates 2— 3—RETMA plugs MECHANICAL INSTALLATION This antenna is a high performance, full size, full wave, 80m loop antenna. A full wave loop, compressed in dimensions has much less than 1 dBd gain. That is hardly high performance, and the stub destroys harmonic resonances that are normally useful in loops. On 40m it is a 2 wave length open loop or Bi-Square.
The HF Active Magnetic Loop Antenna module has been designed to be easy to construct and install, and covers a wide frequency range from 1 to 50MHz.

The IsoLoop is a tuned loop antenna and consists of a band of aluminum (act-ing as a radiating inductor) with a stepping-motor-driven tuning capacitor mounted in series with the band. The LC combination is made to resonate at the chosen operating frequency. The loop has very high Q and the bandwidth is
The AM Loop Antenna can be connected to most receivers by forming a single turn loop, about 6 inches diameter, using a piece of solid copper wire. The 2 ends of the loop should be soldered to the bare ends of a flexible coaxial cable. The other ends of the cable should be stripped back and connected to the receiver, as shown. In the photos we show the loop being held at the center of the wooden cross arms using push pins. Receiver's antenna installation. The wave length of the 2.4GHz is much shorter than that of the conventional frequencies, it is very susceptible 1. The antenna must be kept as straight as possible. Otherwise it will. reduce the effective range. 2. The antenna should be perpendicular to the model.This loop antenna has 2 DB gain over the dipole. It works well on 20 and 15 meter also with compromising results. For an experimenter, it is an antenna worth giving a trial. BEAM (YAGI) ANTENNA. In a beam antenna, two or more dipole elements are used, so the radiated power from the transmitter is added up and focussed in some desired direction ... All in all the installation takes about 2 to 3 minutes. The telescopic carrier has a standard 1/4"-20 thread at the bottom, like it is used for most photo tripods. So you can install the antenna very conveniently on a tripod for operation. The Chameleon P-Loop utilizes a 6:1 reduction gear for the tuning capacitor. The Twin Coil Ferrite Antenna is an active, amplified and tuned AM antenna designed to dramatically increase signal levels of weak and medium strength AM stations. It is a patented design using an ingenious method of extracting the maximum signal level out of its huge ferrite loopstick within the Antenna Element. The Floor loop is designed to be durable and lightweight for the purpose of installing under the floor surface. The material allows it to be covered in concrete or mounted within a hollow sub-surface. The XL Floor antenna is a lightweight antenna with extended detection performance. One of its benefits is easier installation compared to
The AYL-4 K9AY Loop System requires 15 feet in four directions from the center of the antenna, plus addi- tional distance depending on the guying method. The base of the supporting pole and the ground rod are located at the center. With the AYL-M kit, 21 feet in each of the four directions is required.
The antenna is pulled into the air with the antenna support rope. The free end of that rope is tied off near the ground. Usually, the 'antenna support rope' is smaller than the pulley support rope (the one in the tree). Done this way, as the antenna moves in the wind, the 'antenna support rope' moves through the pulley. Apr 11, 2019 · UPDATE 6/13/2017: This turned into a fail. I tested this mount on the mag loop antenna and the weight and balance was too much for the tripod head. The clamp mechanism snapped and rendered the head useless. I removed the head and and am back to using it as before, i.e. with the pvc pipe jammed onto the tripod vertical post. Installation, Antennas and Interference ...
