My RX LOOP is VERTICAL with a perimeter length of 850 feet total. I have not noticed any static built up or flashing regardless of wx. The height is 100 feet, however the TX 1/4 wave inv L up at 100
My 40m loop resonated for RX on 500 khz works well but it is a poor performer on 9 khz connected directly to the sound card, I think the card sees it as a short cct because of the Z mismatch. Other a
From Dave G3YMC G3KEV suggests that loops are very inferior to verticals on 136. He may be right, but experience here is not as pessimistic as he would suggest. I use a loop as a means of getting a s
If you're building a loop don't forget that a lot off turns side-by-side constitutes electrically another loop at right angles to the main one, much smaller perhaps but quite enough to knock the notc

To All from PA0SE Provided you are not too bothered about the deep nulls loop antennas with side-by-side windings are good for DX if they are over a metre in diameter. This construction (see the PA0S
The only accurate way to measure loop inductance for an installation is to use an inductance meter. Calculations do not take into account the loop environment like trees and other objects in the vici
Almost 200 messages so far addressed to me about loop experiments , most are private and what interest fromVK, W, ZL and other places in between and around EU, not heard much from Africa. Some want i
Dear Mal, LF group A couple of suggestions to try with your loop: Hello Jim and some observations on your comments. This is not surprising in a quiet location, since the band noise will define the S
What the heck, go with a 1w signal like the US guys use. You will be surprised as to how many stations you can still work if they have a decent receiver and antenna on their end. This way you won't h
Dear Mal, LF group A couple of suggestions to try with your loop: ...My loop parallel resonated on 136 khz gives about the same signal/noise as the vertical, no discernable difference on RX... This i
Having looked in a couple of web sites and spoken to an experienced 136 khz loop designer/builder in Belgium the conclusion seems to be that the sort of loop size used in Europe/UK in the large loop
Dave/G3YMC my loop configuration is not like yours and is going to have a different feed system, therefore your web site would not be of any interest for my project. I am using parallel capacitor fee
This particular loop is now hoisted into its final position between 2 high beech trees, a convenient place although I would like it to be further away from the vertical/inv L system. Top horizontal t
Hello to all Loop experimenters. especially the USA Thanks to all that have sent me info about their experiments with the bigger loop antennas, especially the observations from the USA, where there s
Has anyone ever tried a large multi turn loop that resonates directly on a LF of interest. Most amateurs cannot get a full size one wavelength loop installed for 160 metres but a 40 metre loop is man
Since installing my 90 metre perimiter vertical loop some months ago and resonating it on 136 khz, I have observed that it is just as prone to QRN/static as the vertical. In my case there is no advan
Well discussion about loops certainly leads to strong views on this reflector! Bill is correct in saying that the satisfaction in using them is that many say they don't work! Those with big plots and
Regards Martin Maynard Slightly off topic but can anyone explain the workings of the feed arrangements of loop antenna. Am constructing a loop of 1.7 meters diameter made out of 52inch tube rolled
