DIY: How to build a Noise-Cancelling Passive Loop (NCPL) antenna
2020年4月5日 · I’ve gotten an number of inquiries from SWLing Post readers asking for a step-by-step guide to building the passive loop antenna I’ve mentioned in a number of previous posts. This antenna is the homebrew version of the commercially-available Airspy Youloop. It works a treat. And, yes, folks…it’s fun to build.
Homebrew Loop Antenna Brings The Shortwave World To You
2020年4月13日 · The lossy, untuned, electrically-small antenna, whether a vertical, loop, or horizontal dipole, turns out to be an excellent transducer for HF skywaves.
Loop-on-Ground, the simplest Receive-Antenna you will ever …
2020年1月4日 · If you are struggling to get a good Receive-antenna for 160 meters, I highly recommend this Loop-on-Ground design. Your mileage may vary, but I would be surprised if you do not have a favorable result, and you will never build or install a simpler antenna than the LOG.

These loops are made to enhance radio reception in the broadcast, or medium wave (MW) band range. Some of the loops are just one coil, some have tuning capacitors and some have an extra coupling coil. Read on and discover the fantasy of loop antennas. Or fetish in my case.
Making a Receive Loop Antenna - The RadioReference Wiki
2016年3月31日 · Tuning a loop with a capacitor right at the feedpoint is great - although it may be impractical. One option is to tune the system as a whole in the shack near the radio. That is, you can buy or build your own so-called antenna-tuner, and tune out the complex impedance presented by the whole structure. Common L-type or T-types work.
How to build SM0VPO’s 20 meter magnetic loop antenna
2018年5月30日 · In particular, we both were impressed with Harry’s 20 Meter Loop Antenna–it’s such a simple project and requires no special order components. In fact, all of the components (save, perhaps, the antenna connector) can be purchased at a DIY store.
And if you follow the steps, you should have yourself a nice loop antenna that works well and fits at almost any QTH. Let's build a loop for 20 meters that exhibits around 65% efficiency. We'll make it out of .5 inch copper pipe and each side will be 3.5 feet long. This loop is nice because is it so light and easy to place pretty much anywhere.
How to build a tuned loop antenna - IW5EDI Simone - Ham-Radio
How can you vastly improve your Medium Wave reception? its quite simple really, all you need is 120 foot of wire, a few lengths of timber and an old tuning capacitor with which you can build the answer to every DX’ers prayers, a tuned loop antenna.
SWLing Blog: Building a Homemade YouLoop (Noise-Cancelling Passive Loop ...
2020年4月6日 · The YouLoop is a passive loop antenna designed for HF reception, but also works well up until VHF. The main catch is that you need to use it with a receiver with a low noise figure front end, like the Airspy HF+ Discovery (SDRplay units should work well too).
How to build a Milk Crate AM Broadcast Loop Antenna
2017年6月8日 · Loops are considered bi-directional in that they receive to the front and back, but not to the sides. The tuned loop antenna quickly became my weapon of choice for medium wave DXing. Recently when the weather began allowing me to enjoy the outdoors, I decided to make another smaller loop antenna from a plastic milk crate I had lying around.
