Jun 05, 2017 · For my purpose this turned out to be perfect as I was only interested in covering the 40 meter band which is 300khz wide. Measuring the capacitor it is roughly 5pF to 20pF. Close up of capacitor and connections -AC9LF. To resonate the main loop at 7Mhz with 4.6uH of inductance I needed roughly 113pF of capacitance.

My magnetic loop inspired by DG2IAQ’s design. I have long been intrigued by the magnetic loop antenna and have been reading widely on the Internet on the subject for some time. I also saw Tony VK3CAT’s AlexLoop and thought it would be fun to try and make my own as an interesting alternative antenna for SOTA. Unfortunately, most hams think low power equates with poor antennas. Many QRP operators seem to delight in using their rig with a 50-foot piece of wire thrown out the nearest window. The basic rule of QRP antennas is that nothing beats a beam; and nothing beats a beam on a tall tower. Put up the best beam/tower combination you can afford. The Wonder Loop compact QRP portable loop is perfect for attaching directly to your ft-817 or QRP transceiver for an easy-to-use, instant portable hf antenna solution. We have tested this loop in-store and worked around Europe on only 10w! We will be uploading videos of some of our contacts very soon,Check out the impressive specifications of this little 'wonder'!*17" diameter self-supporting ...The coupling loop features a novel hybrid coupling scheme that guarantees a match of 1.2:1 or better from 60/40-6M when the antenna is mounted in the clear. No other US loop can make this claim. Compare this to our competition. In addition, the coupling loop assembly easily adjusts in height to guarantee an optimal match on all bands.The Wonder Loop compact QRP portable loop is perfect for attaching directly to your ft-817 or QRP transceiver for an easy-to-use, instant portable hf antenna solution.

Small loop antennas are often referred to as magnetic antennas. This is because they mostly respond to the magnetic component of an electromagnetic wave and transmit a large magnetic component in the extreme near field (<1/10 wavelength distance). In the far field (>1 wavelength distance) the RF from a small loop is the same as that from any ... bloated face meaningbmw car perfumeinstall pip fedorabrock grain binsboise river water levelmodel railway dropper wirescookies high flyerstraffic accidents today near mestar washers push on fixnebraska baseball todayused mig welders for sale near medecathlon swimming costumepark model trailers for sale in parkscareer online high schoolhonda 300ex 2002sepex dc motor controller status lightdog adoptionbpd ex unblocked meprefab homes near meanthropologie dining chairsworld cat 325samsung refrigerator water filter bypass plug xp
