Joe Giraudo: Is there a reason you flattened out the tubing for the smaller loop? Does it affect performance?
Coil Smoke: Why is the exciter(ed) loop not centered in outer loop ?
joen7xxx: Excellent video! I have the bug now. What are your dimensions for the loop that covers 20 meters and above? Also, what value capacitor did you use for this loop? Thanks!
revo adan: Thanks, what value of Air Caps will i use to TX 50-75watts with 1inch tube at 13ftloop? bit so confused of the PF and Voltage value. I know theres a lot on the internet but still confused.
Argento Goldspier: Excellent clear interesting videos. I am going to make a magnetic loop soon for fun. Here is a web page I found for measurements http://www.66pacific.com/calculators/small_tx_loop_calc.aspx from what I can gather 27MHz with 19mm Copper Tube Between 1.3 to 2.69 meters Circumference, 28 MHz Between 1.3 to 2.6 meters Circumference , 3.5MHz Between 10.4 and 20.8 meters Circumference, 7 MHz Between 5.2 and 10.4 meters Circumference, 14MHz Between 2.6 and 5.2 meters Circumference, 21MHz Between 1.73 and 3.46 meters Circumference and like you say 1/5 smaller is the driving loop. They say the loop radiates from side on but yours gave best when the circle or face was in the direction of the field strength meter.Your soldering iron brings back memories of when I used that type back in the early 80's. Nice to see a blue Weller again. Thank you
Gabriel Sierra: Thanks for the video. I used a 50uA meter I got on the internet, wish my meter was as small as yours.
fredintheshed1: Thank you for sharing and explaining things so clearly. Enjoyed the video. Subbed.
Nurul Farahain: Hello sir. I am glad that I have found this video. It is really a good video. Actually, I am doing my final year project and i have searched the calculations to build this antenna. But, i couldnt find it. I hope i can learn the calculation from you, sir. Thank you. And the frequency that i need to analyse is 1 MHz to 10 Mhz . And again sir, thanks. :)
Philip Gardner: Thanks for this video. It's clear and well presented. I am in the process of making one as we speak. My configuration calls for a 22 pF tuning capacitor. Thanks again.
dale myers: what size loop would you suggest for 40 to 80 or 40 to 160. also would larger diameter copper tubing be more suited for lower band freq's? larger diameter copper would make a lower band loop more sturdy in bad weather. and i can only imagine that it would be good to paint it or plate it with gold to reduce oxidation.... that is if you plan to leave it out once set up for permanent use.
ASO: Hi! MY FRIEND . How are you. Could you send me the circuit diagram of the antenna? OR LINK ,,FOR CONSTRUCTION ANTENNA LOOP best regards.... TKS/73 BRAZIL ECOCHOOPER@HOTMAIL.COM
echo xray: Excellent ! this is far the bes magnetic loopt i have seen looks mint....BTW just wondering if these radiate same as a yagi with driven elents etc. looks to be so to me so the possiblitities are endless in construct thanks for posting M6MRG 73/

dale myers: another great thing about the loop antennas. it being narrow banded means the antenna becomes a filter itself. so your equipment can have a certain amount of harmonics and the radiator can't effectively radiate them. then they are trapped and spent as heat.. and heat isn't that bad, when the antenna can de-ice itself. great video sir. i will be making one soon. but i first must buy a hf rig. after all these years and finally passing the amateur-extra. i have yet to work hf other than 10 and 11. 73's kf4dcy
