Use that PAR EF-SWL for a noise pickup antenna for a MFJ-1026 or Timewave ANC-4 to complete Hello all, New to this group and I have been researching various types of recieve antennas to complement my stations vertical antenna. 5V – 20V and maximum current: 300 mA max with insertion loss of < 0. 05-30 MHz: Bandwidth: Gain:? dB: The loop itself is provided by the user The Wellbrook claims to be a magnetic loop, but everything I have ever read about loop designs requires that if they are to work in the truly "magnetic" mode, they need to be brought to resonance, and when a short antenna system (I say system, because all antennas are "systems" that comprise of element, feeder and, if needed, additional matching elements) is made Hi there, so I've managed to assemble the loop and make up a 15 metre 50 Ohm coaxial cable with two bayonet-type BNC plugs. Had it set up on an Icom IC R-8500. To optimise the power transfer, the Compact – need for small compact antennas in a city environment, use in garden, indoors or loft, portable. We asked him to make some real time comparisons of some popular active loop antenna amplifier designs using real signals to help give people a practical feel for how well they work against that well established favourite – the Wellbrook 1530AN. Overall, inside antennas will pick up more noise than outside ones. tinyurl. Their re-engineered Active Inoor Loop Antenna LA5030 would serve you well. The loop antenna is a Wellbrook ALA1530S+ is a 1 m diameter loop antenna. Loop rotation for me is a function of trying to null out local qrm and not signal improvement. My antenna setup is similar to Wellbrook’s commercial flexible loop; Wooden base for the antenna (ALA1530 is bolted to the base) 20 feet of lightweight RG-174 coax I currently use 4 x HF antennae in a fixed installation. Active Small Loop Antennas Motivation 1. I have a Tecsun PL-360. Joined Apr 5, 2015 Messages 11 Location no INDOOR antenna -- will compete with an When I first got into magnetic loops in 1998, I played around with homebrew designs, but finally settled on the Active Antenna Amplifier from LZ1AQ, which performs really well. Instead, my Wellbrook ALA1530LN-NA magnetic active loop receiving antenna spares me the trouble. Like some others I find the Wellbrook ALA100LN loop module a real good solution with better results. If you own the W6LVP loop and/or have compared it with the Pixel or Wellbrook, please comment! The WellGood active loop antenna tested in combination with the Airspy HF+ SDR Matthias DD1US, Updated March 6th 2022 I was always interested in active loop antennas, especially for portable operations. It is much smaller and therefore much cheaper than your To my knowledge, the W6LVP is one of the most affordable larger diameter amplified wideband mag loop antennas. Shipping the Wellbrook antenna from the UK to the US adds about $100. Maybe in some ultra quiet location or under very strong local interference Wellbrook is better. All my shortwave listening is accomplished with either a Pixel RF Pro-1B loop or a Wellbrook ALA-1530LNP NA antenna. Loop antennas for outstanding directional radio listening and reception monitoring of medium wave, long wave, short wave and HF DX. I spend most of my time on the ham bands and occasionally I enjoy SWL. Someone here will undoubtedly suggest a Wellbrook active loop antenna for your balcony. 26dB; thus allowing for use with a smaller loop. Lots of talk, no proof; again, having the MLA-30 (plus) in my hands and having other antennas (and having tried more in a past), the MLA-30 may be modified to become a pretty decent active loop, but even then, it won't be up Find out more about this product here: https://www. What's new. Second Hand Wellbrook ALA330 Receiving LoopActive Loop Antenna ALA 330S (aluminium)3MHz-30MHz 1. +44 1425 674174. It’s nice to have an alternative to the pricier Wellbrook and Pixel Loop antennas. Click here for a loop antenna rotator control diagram. I was about to buy this antenna, but now I know it would have been a mistake. active loops are excellent for reception from longwave & medium wave upwards. In a high RF noise urban environment (almost everyplace not "out in the country" these days) the active loop (something like In this video Mike Harwood compares the LZ1AQ active mag loop antenna with the Wellbrook 1530AN at a couple of frequencies using an SDRplay RSPduo which allo In that respect we found that on medium wave the Wellbrook loop was much better than the Liniplex loop we tested a few years back, but not quite as good as the indoor mediumwave loop from KIWA. I’ll try going up to the roof of the parking garage. 01425 674174 Int. This antenna has several advantages, not least being only 1 metre diameter! This loop relies on being horizontally polarised and receives only the magnetic wave, thus as most noise in the domestic environment is vertically polarised and A brief introduction for those not familiar with the Wellbrook Communications K9AY loop: The antenna uses two, or four, delta-shaped loops to provide a steerable cardioid pattern in 90° or 45° steps. This antenna has several advantages, not least being only 1 metre diameter! This loop relies on being horizontally polarised and receives only the magnetic wave, thus as most noise in the domestic environment is vertically polarised and Back to Antennas Next antenna Last Wellbrook ALA100M SPECIFICATIONS. Antennas/Magnetic Loop; The title of the main category is Magnetic Loop and it deals mainly with Magnetic loop antenna projects. 2) Broadband untuned loop – the commonest designs are by Wellbrook and these are small (~1m diameter) , usually circular and lightweight. P. No doubt, the venerable Wellbrook loop has helped thousands radio enthusiasts mitigate RFI/QRM and make it possible to once again DX from home. If you are limited to indoor antennas, I'd suggest a loop of some type would be almost mandatory to avoid noise problems from your own devices. I forgot to mention that my Wellbrook is connected to a Drake R8B, a receiver that handles strong signals very well. W6LVP sells two versions of the This is a comparison file of weak signal reception with the two models of Wellbrook Communications “Imperium” series loop antennas: the ALA1530LN “Pro” Imperium and the ALA1530S+ Imperium. But since I got my Wellbrook ALA1530S+ I have not used another loop, my home brew loops that I have used for years are not even currently hooked up. My use of the ALA 100 is primarily for DXing foreign medium wave signals, with a secondary use of hearing third-world broadcasters on the tropical bands. I actually own the Pixel Loop and might very well purchase, review and compare the W6LVP loop later this year (if time allows). I have several indoor loop antennas, but we have so much in-house interference, they are of little value at my location. Each side is 8. For my use (HF only, some strong local AM and FM stations, fairly noisy residential area) even LZ1AQ is an overkill. Thanks for such thorough review. For these, I use either an indoor slinky antenna I It’s nice to have an alternative to the pricier Wellbrook and Pixel Loop antennas. It hears stuff down there the wire would not even dream of. Wellbrook ALA-1530; Wellbrook ALA-330. See below -- After three years, it's pretty beat up.
