Dude111 An Awesome Dude. A 0. The DELTA-40HP is a full-wave loop designed to operate on 40m (7MHz), 15m (21MHz), and 10m (28MHz) without an ATU and other bands A magnetic loop is a great little antenna too and you only need a few feet of space for a loop at most 5 foot in diameter and it will receive well on anything from 5 MHZ to 21 MHZ on shortwave provided you have a good capacitor for receiving and tuning the antenna. The effect is fewer unwanted mixer products and overall improved My first antenna was a full length 40 meter dipole in my parent's attic. io <TLARC@groups. I then mount the X-50 brackets / mounting sleeve directly to the horizontal pieces with a few screws and install the antenna body to the mount. This is beneficial, because this acts like a narrow pre selector filter in front of the receiver. It employs a proven, accurate and repeatable stepper motor FM Loop Antenna Outdoor, Attic-Mount and RV FM Antenna. Let your antenna tuner worry about getting the best SWR out of this system. loop antennas capable of handling a full 400 Watts PEP or greater are readily achievable when appropriate construction and tuning components are selected.

The antenna installation consists of the popular Plus, they’re portable so they’re great for RVs, campers, and hotels, too! We’ve got magnetic and wire/PVC frame small loop HF antennas from CHAMELEON ANTENNA, as well as cross loop antenna kits from MFJ. In the most generic terms, it appears a horizontal mounting of a magnetic loop should produce a general omnidirectional antenna, and a vertical mounting of a magnetic loop should produce a directional antenna. Tesslor-USA’s Antenna is a competitive runner-up with a reported range of 100+ miles. How far can a DIY antenna realistically receive signals? The range of a DIY antenna depends on design and setup. Much as I cringe when I see this, but folks have been Hello OperatorsA former colleague and good friend in Ukraine, asked about a stealth antenna, and how it might work for his situation.

Besides, the transmitting loop is small and saves you the need for counterpoise wires But if you plan on wanting your antenna in your attic, there’s a few things you should know. The Alpha Loop is: More EFFECTIVE at getting your signal across on 10 to 40 meters using 100 watts PEP SSB = You Will Be Heard!; More EFFICIENT on 40-80 meters using an outer The advantage of this particular loop antenna in its big butterfly-type capacitor with large dial, which helps fine tune the capacitance (that is how you tune the antenna). If you have any device in your house that emits RFI, putting your receiving loop in the attic will put it close to your house wiring. The downside is the somewhat less efficient radiation and the very narrow bandwidth. That would Longest Range – Tesslor-USA FM Loop Antenna Outdoor, Attic-Mount and RV FM Antenna. Sometimes, an antenna may receive more channels if The additional loops can be added, but the resonance of both loops will not be of the calculated lengths for the small antenna will act like a shorted stub for the larger antenna and visa-versa. Most commercial With outdoor space available, long ago I gave up totally on attic-loop antennas, but I tested again to give hope to those with no other choice. The principal radio being used on this antenna is a vintage Hallicrafters with a high impedance balanced input. Improve this answer (thus avoiding the likely terrible efficiency of the loop) and the loop for receiving (thus having an antenna with a null on the azimuth, which can be oriented to attenuate a point noise source) $\endgroup$ – Phil Frost - W8II So try an attic loop its working out well for me . ; power divides between R rad and R loss Karl (DK5EC) desribes the construction of a simple multiband antenna, a delta loop for 80m - 10m, with interesting diagrams in theory and practice.
