The prevailing truth in the Shortwave world is that you spend on the Antenna! You can have an expensive Radio that won't pick up squat! Co6aka, you're right, but the point here is trying to improve the existing MLA-30/MLA-30+ loop; now, the preamp circuit is fully potted and un-potting it would be quite a hassle and may result in damages to the board, so I decided it won't be worth going that way, what I'm planning is a series of modifications to improve the existing circuit/antenna without too much Nor I did, but time ago a friend lend me one for some time, and it's a good antenna, it has some hardware design flaws, but other than that, it works very well, the preamp was designed to reduce both noise and intermodulation to very low levels; comparing the MLA-30 to a WellBrook (or other high level loops) isn't fair, it's like comparing a cheap car with (say) a I'll evaluate it to the W6LVP and Hiletgo loops after I figure out what is up with the hot transistor or after I get another board finished. “These are not formal technical drawings but show what the systems comprise of, illustrating plant equipment, including services and control valves, any components potentially relevant to the MLA 30 is a great Antenna and I don't think you should buy more expensive loops A circuit schematic is a visual representation of an electrical circuit. Will I need anything to turn off the 12VDC loop's power when transmitting? Or does the Flex do that for me? And how far away from my transmitting antennas should I install it? Thanks & 73.

Wire antennas work well and I would choose a wire over that loop. Thus when input A rises (before input B), this results in Q a being high but Q b still low. Assembly of the antenna is extremely straightforward. Mine got blown over one time and broke a BNC. Recently Martin (G8JNJ) reverse engineered the active circuit So the W6LVP loop is the winner, but not by a huge SNR margin. I was surprised to get a response with technical information within an hour or so. When using the W6LVP mobile loop with a transceiver not having a separate receive antenna input and without a power amplifier, connect it as follows: Connect a short 50-ohm cable with I’ve just finished building a variation of the W6LVP amplified magnetic loop antenna.

E Many thanks to SWLing Post contributor, Kenneth Wigger, who writes:. My current loop is a year old and the design is improved with the electrical connections to the loop being made by flying leads which should make it last more than 10 years! Compared to a 100ft doublet at 30ft the Wellbrook is generally only slightly behind in sensitivity from 2-30MHz, but is ahead of the doublet below 2MHz especially since the Only 1 hour of tests and I can tell you the MLA 30 seems as good as the W6LVP loop I am totally surprised As a weapon in my battle with local background noise, I also have an untuned amplified receive-only 3 foot diameter magnetic loop antenna connected to a second receiver and then to a second copy of FLDIGI – poor man’s diversity. They don't get used much. My current loop is a year old and the design is improved with the electrical connections to the loop being made by flying leads which should make it last more than 10 years! Compared to a 100ft doublet at 30ft the Wellbrook is generally only slightly behind in sensitivity from 2-30MHz, but is ahead of the doublet below 2MHz especially since the I've read there is little difference between a Pixel, Wellbrook and W6LVP loop and the W6LVP is about half the price.

Wellbrook Medium Aperture Active Loop Antenna Model ALA100LN. But the cleaner, stronger signals of CHU Canada on 3339 kHz and 7850 kHz, as Today we will use the W6LVP loop antenna on several portable radios to test how they handle the signals I received my loop today and so far hf aero has been very impressive on all bands even on 3. The overall consensus from the reviews was that it worked decently for the price, but of course could never live up to the high end loops that cost hundreds of dollars. W6LVP sells an experimenters kit that includes the amplifier, power inserter and low-noise power supply for $185 including shipping. From some preliminary comparison tests on SW with the Mini Whip the loop is These loops are typically around 150-200 ohms impedance at the feed point and input to the preamp and there is no need for a huge conductor like on a magnetic transmitting loop which is very low impedance. A well designed Wideband Active loop will provide good performance and often rival full-size antennas rejecting local Man-made noise while delivering a good Signal to Noise Ratio in the process. To my surprise, signal strengths at the high end of the band (1520 KHz) remained essentially the same for all three loops, rising only about 3 dB (half an S-unit) with the 4 meter loop. The antenna will be installed at The W6LVP loop amplifier is potted and a schematic is not provided but, George Smart https://www. Derivative control mode iv. Enough of a signal to hear WDIA 1070 Memphis from my home near Star I compare the receive signal and audio between both the Zero Five 43' Vertical vs the W6LVP Magnetic Loop Antenna. S. I was able to purchase the preamplifier, power inserter, and the power supply separately. The last schematics is the output jacks connections both between them and to the relay board. It has poor sensitivity at MW and very poor sensitivity at LF. The Wellbrook loop amp is designed with a much lower input impedance at LF and works much better at LF as well as at MW and HF. Those are quite simple features to implement if necessary, so if you have seen one parallel loop schematic, then you have pretty much seen all of them. I am curious to see how the loop coax shields are connected to the pre-amp box. Joined 2011. This was during a weekend 160M contest. gregom Newbie.
