Introduction The purpose of this section is to provide the information necessary to make rational decisions on products, with the goal being to connect to the Internet from your RV. The idea is to make sure that all of your local devices – computers, tablets, wireless printers, TV, DVR, etc. In a home environment meaning a “fixed” environment only one method is typically used to connect to the Internet – often that is DSL or Cable. This is typically a “cellular router”, meaning that the router can have a cellular aircard plugged into it and use that as a method to connect to the Internet. Ideally, only the router “knows” about the multiple methods of connecting to the Internet. It manages all of those methods and presents a single network to your devices. That way the devices do not have to be configured multiple times as you move locations.

Magnetic Loop Magnetic Loop Antenna Project The small magnetic loop antenna is a compact efficient antenna that is ideal for portable operation or limited spaces and can be improvised inexpensively. Since its radiation resistance is low and circulating current large, the loop must be constructed of a low resistance large outer diameter conductor for best efficiency. Typically, magnetic loop antennas can be built from coaxial cable, hardline, or solid copper or aluminum tubing or ribbon.
These loops also have a very narrow bandwidth, requiring a variable capacitor for tuning to the operating frequency. As voltages on the order of thousands of volts develop across the capacitor, air variables or vacuum variable capacitors are used. To maintain the lowest series circuit resistance, the connections are preferably soldered and a split-stator or “butterfly” capacitor is preferred.

The Twin Coil can double the signal strength of any weak station during the day. The antenna was designed to work with everything from portable radios without antenna connectors to home stereos with wire antenna terminals. Its wireless ferrite stick works on radios without antenna connectors, while the typical wire patch cord functions with radio antenna connectors found on stereos. In this case the additional antenna will only help with very weak signals where improvement is not already noticed.
If you have a favorite AM radio station but experience poor reception at the exact place where you want your radio, the Twin Coil can increase your AM radio reception significantly. The antenna element is capable of picking up a clean signal some distance from your radio and sending it to the radio and overriding the static. This feature alone can make it the ideal AM antenna because there is no other way to get a clean signal. It has the highest gain of any commercial AM antenna.
The antenna element has directional characteristics.

It is designed for portability, and can be assembled or disassembled in about a minute. When disassembled the antenna easily fits in a suitcase or backpack. The Wonder Loop is the perfect antenna for picnic table or hotel room operation, or for home station use where outside antennas are not permitted and attic antennas not possible.
MTM Scientific, Inc Pickup Loop for AM Loop Antenna. The AM Loop Antenna sold by MTM Scientific, Inc is designed to be used with a portable AM radio. The coupling from the antenna to the radio is through the ferrite loop antenna inside most portable AM radios.
You can get the channel frequencies off the FCC website. Then I make one for them. Try not to OD on Seinfeld! J Lou 1 meter equals Just remove the insulation and straighten it out. I would put all wires, bow ties and the running wires, under the washers as you see in the photographs.

We have carried out some very exciting tests of C. In our tests the AM radio reception has improved dramatically with this antenna. This is the perfect product whether you are living in a country area or in the city and need to improve your AM radio reception on your favourite radio station. Also, if you live in a bush fire ‘prone’ area and need stay in touch with the situation on critical days, this Sangean AM antenna will assist. So what makes this antenna different?
First let’s have a quick look at the various options for AM reception.
Apr 20, · A Dynamite Antenna for an AM Radio. By RangerJ in Technology Electronics. 93, 5. I rigged up one of these antennas, making a loop under the glass counter top. The difference was remarkable; all we had to do was hold the radio near the counter and signals would jump out of the speaker. I’ve used a tunable loop antenna.
That is certainly the case with the basic “loop” antenna, an often misunderstood critter, but one that gives absolutely the most for each foot of wire of any antenna I have had occasion to play with. They are long, long, long Who has room for over feet of wire in the case of a full-wavelength loop for meters? Won’t that thing become the perfect conduit right into my house for lightning and other “wrath of God” type things?
And will it work on more than one band? I don’t want something that big in my yard if it only gets me a narrow swatch of one band. First, let me reassure you that such an antenna does not necessarily take much room. One reason I went to one in the first place is because I didn’t have room for a foot-long dipole for and I wanted to give the “top band” a try for the first time in my 45 years of being a ham. If you are talking 75 meters and up if you want a multi-band antenna

When I was a teenager, I used it with my old Realistic stereo receiver to improve its AM reception, and it did work. My dad put it up for me. You might also find it from other electronics suppliers. Find two points, such as two poles NOT utility poles!
When I searched on “AM radio antenna design”, You are transforming the 4-conductor telephone cable into a loop with 4 turns of wire. 6. If the wires aren’t too long you can hold the loose ends up with one hand while turning the antenna assembly below them. Watch out for kinking.
It is also a very compact design lending itself well to a variety of mounting options and locations inside and outside. Outside will give the best performance. The Pennyloop antenna started out as a single loop antenna and could be used with a reflector. It was found through extensive testing, at least in my area, that the UHF signal strength is very “layered”. A single loop antenna, or even a simple thick element dipole for that matter, would pick up all of my distant stations – Just not at the same height!
A new design emerged from this common issue with UHF signals. The antenna did not need to be excessively tall, but needed some additional height to cover each of the signal layers at the same time. This design goal was achieved in the Pennyloop by having a second loop installed on the original feed point. It served several purposes. It increased the gain substantially, focused more on the horizon where the signals were coming from, and gave the additional height needed to be in each of the signal layers simultaneously.
As with all antenna designs, there are compromises.
Antennas Home-made antennas can greatly improve the performance of AM and FM radios, short-wave receivers, and scanners. If you are a talk-radio fan then experiment with the AM band antennas and you will be able to hear shows from all over the country with surprising clarity. Short-wave receivers are always coping with weak signals and they must have a good antenna to perform adequately. Scanners can pick up local police and two-way radio with the little telescoping antenna provided but with good antennas a scanner becomes an amazing ear on the world nearby.
No pre-amp, filter or other receiver refinement offers anywhere near the level of performance improvement t that a well-designed antenna offers. The results can be quite satisfying, leaving no doubt that the project was well worth the effort.
To connect an external AM antenna, follow these steps: Insert the AM antenna plug into the AM Antenna jack on the back of the Bose® system Place the circular loop of the antenna as far away as possible from sources of electromagnetic interference, such as fluorescent lights, dimmer switches, etc.
TV antennas have compromises built in.. All of this it tied together and the efficiency is greatly compromised. Also, there is no elements cut for the 3-meter FM broadcast band. You must rely on the VHF-lo elements, which are designed for Mc. This has directional selectivity limitations: Because the wavelength of the signal is too small for the VHF-lo elements, the antenna’s front to back ratio it’s ability to select signals directly in front of it, but reject signals from behind is very poor to nonexistent.
TV antennas tend to have many lobes, scattered around the azimuth plane, looking sort of like a starfish pattern, at Mc. The behavie psuedo omni-directionally at these frequencies.
