loop antenne voor 40160 meter (1,87,0 MHz)
The band noise on 160M is drastically reduced on receive using the loop. The typical daytime noise floor on the wire antenna at this QTH is S-5 and this reduces to S-1 with the loop.
Final lift attempt of 160 40 meter loop antenna YouTube
Here's an intriguing way to get on 160 and 80 meters with a stealthy magnetic loop antenna. In this video, Kevin Loughin builds, erects, and uses a 6-foot/1.829 meter diameter magnetic loop for 80 and 160 meters. As Kevin relates, " I create a two-turn loop to get down to 160 and it works quite well.

While 1 wavelength loops radiate broadside to the plane of the antennas, larger sizes tend to radiate more off the edges, and may have a broadside null. With larger loops (in terms of wavelengths), the patterns can have multiple lobes and nulls. We most often encounter this when we use a single loop antenna on multiple bands.

March 11, 2022 Antennas for the 80 and 160 meter Amateur Radio bands can present a difficult challenge for radio amateurs living in restricted housing or on small urban lots. If you're facing this situation, this magnetic loop antenna from Kevin Loughin (KB9RLW) could get you back on the air.
The G4AXP / VK6MC Top Band Loop Antenna
Magnetic loop antenna for 160 - 15 metres Another item on this website discussed antennas that amateurs use to operate from confined locations. The smallest antenna described for 80 metres was a magnetic loop. This article provides details needed to build your own. Description Below is a diagram and some construction details.
160m loop antenna 160 meter loop antenna design Aep22
A novel phased orthogonal loop antenna is used to create a rotating magnetic field source, which creates low frequency waves called Alfven waves (80 to 355 kHz) as described in 6. It requires a.
Build a 160 80 Meter Loop Antenna Part 1via torchbrowser com
Most new hams quickly learn that the high-frequency bands are where the action is, and getting on the air somewhere between 40- and 160-meters is the way to make those coveted globe-hopping.
[TowerTalk] 160 meter receiving loop antenna schematic has beenposted
Sorted by: 1. The cheapest solution for the 160m band is probably a magnetic loop antenna, but do be aware that these antennas are optimised for small space and low cost, and NOT for performance. A magnetic loop is an extremely high-Q antenna with a very tight bandwidth (think ~5kHz on the 160m band), but they are tunable.

HF Loop Antenna Wire Kits (16010 meters) Loop Antennas Palomar
The skywire loop is an excellent antenna - they can be a bit of work to get up in the air if you have a lot of obstacles (trees, xyl, etc.) but it is worth it. What's the right length? 574' feet The length of a loop best suited for operation on 160 meters is too short for use on the higher bands.
loop 160 meter.
10 foot coax jumper from loop balun to tuner input. Common tee-type C-L-C antenna tuner. The loop seems nearly omnidirectional for medium to high-angle skywave signals, yet has great noise-nulling directivity at very low angles from 160 - 20 meters. These two qualities make it a great general purpose antenna especially indoors.
160/80m Coaxial Loop Receiving Antennas
Three and a half to four foot loop antennas for several of the HF bands from 160- to 10-meters. A low-profile, compact antenna made from copper tubing and using a small D.C. motor to remotely tune the capacitor. Another loop for 20- through 10-meters using a novel "trombone slide" arrangement as a tuning capacitor.

K3ZXL 160 Meter Loop
An early version of this type of HWV antenna for 160 meters was the "rubber duckie" antenna developed by Joe Moraski, KY3F, in the early 1990s.3 This antenna was constructed using two 10 foot sections of 4 inch PVC pipe joined, two lengths of 140 feet of #18 wire, and wound at 1 turn per inch over each 10 foot section and the wires connected at.
