Loop antenna - Wikipedia - If a small loop antenna's loss is 50 dB (as if the antenna included a 50 dB attenuator) the electrical inefficiency of that antenna will have little influence on the receiving system's signal-to-noise ratio. In contrast, at quieter frequencies at about 20 MHz and above, an antenna with a 50 dB loss could degrade the received signal-to-noise ratio by up to 50 dB, resulting in terrible ...

Working 160M From a Small Lot (and Larger Ones Too) - short antenna so it looks longer to the transmitter (often resonant) ... Handbook are very accurate. How Much Top Loading? • Use NEC to predict • Even a very simple model will get you close for the radiator • Connect the bottom of the vertical wire to ground, add a source at the bottom, add the top loading wire(s) • Plot SWR in 10 kHz steps to find resonance • Vary length of top wire ...

80-20m Mag Loop - Nonstop Systems - They are also small enough to rotate with a small motor, or TV-antenna rotor. They are less conspicuous (to my friends of the home-owners association "police") than a wire antenna that is strung along the outside of the building. I don't want to have to mess with radials, counterpoises, RF-grounds, etc. Loops are inherently symmetrical, like dipoles. Can be installed close to the ground ...

Cellular & Wi-Fi Antenna Installation Guide for RVs and ... - Bookmark. Installing Antennas. Once you've decided on your Wi-Fi and cellular signal enhancing antennas, the next challenge will be installing them on your motorhome, travel trailer, 5th wheel, motor yacht, trawler or sailboat.. Installation of mobile antennas can be tricky, especially since the components must be secure, unobtrusive, weatherproof, and abide by any height limitations.

Army Weapon Systems - USAASC - Here you’ll find more about the systems that enable our Soldiers to remain flexible, adaptable and agile to meet the needs of combatant commanders. For a more in-depth look at these systems throughout the years, consult the Army Weapon Systems Handbook archive.

Discone antenna - Wikipedia - A discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath. Omnidirectional, vertically polarized and with gain similar to a dipole, it is exceptionally wideband, offering a frequency range ratio of up to approximately 10:1.

Welcome To Antennas 101 | Electronic Design - This kind of antenna is great for very small signals, such as those from satellites. Are there any other common directional antennas? Another excellent directional gain antenna is the phased array ...

AA5TB - Small Loop Antennas - The ARRL Antenna Handbook's equations helped me put a little design effort into these antennas so that I could make them work the way I wanted them to work. These days the Internet is a gold mine of small loop antenna information. I find small transmitting loop antennas very useful when space for a full size antenna is limited. When care is ...
