Ciro Mazzoni BABY Automatic Magnetic Loop Antenna provides transmit and receive continuous coverage across 6.6 - 29.8 MHz which includes all of the 40 - 10 meter HF amateur radio bands. It is made of aircraft grade aluminum. The tuning capacitor is an air-variable type made of thick aluminum plates. Each set of capacitor plates is welded directly to opposite portions of the top of the loop.Ciro Mazzoni BABY Automatic Magnetic Loop Antenna provides transmit and receive continuous coverage across 6.6 - 29.8 MHz which includes all of the 40 - 10 meter HF [[amateur radio]] bands.

This is no flimsy MFJ plastic easily broken ham toy. This antenna looks and feels like a well built commercial or military grade piece of equipment.To perform testing the antenna will be mounted on a pole 5' off the ground and connected to an Icom IC-7600 transceiver. Test results will be shared here...Initial finding is that the antenna seems to perform strongly on 20 meter and secondly on 40 meter, with the lowest SWR on 40 and overall best signal reports on 20. Initial testing on the 10 meter band were inconclusive or perhaps somewhat disappointing.On the 20 meter band signal reports from distant stations stated a strong and clear signal. More testing will be necessary under different band conditions, however, at this point the results suggest the antenna radiates well but may not be ideal for reception of very weak stations. Yet, that may not be true because although signal reception levels are lower compared to the dipole, the noise is dramatically reduced. This antenna is "quiet" in that local area man made noise is almost completely eliminated. This makes it easier to "hear" and discern voices on weak signals that would otherwise be lost in the noise.There is some directivity in that it does not behave like a beam but does have a distinctly present null. Rotation of the antenna is not needed as frequently as would be with a beam. Setting a general direction suffices unless you want to make a significant compass direction change. I would suggest that beyond 45 degree increments, fine rotation is not necessary at all.Criticisms of the documentation are warranted. You will find yourself conducting some trial and error on things that could have been eliminated by proper documentation. Some of these shortcomings will be documented here as time permits.== Assembly and Installation Tips ==Since the instruction manual covers assembly and installation the process will not be repeated here as the manual is available free online from DXEngineering (recommended) and from the manufacturer web site (same except larger document in many languages.) What will be covered here are some tips and suggestions that will be helpful where the documentation fails to provide adequate information as well as some tips based on experience with the antenna system.Issue #1: Documentation at the time of this writing does not describe proper wiring with regards to polarity for the motor controller wiring from the antenna to the station control unit. Wiring backwards will result in an error on the controller unit.Issue #2: Initial movement and bolt/screw torque. You may have to loosen bolts at movement points or where it is hinged. You may also have to physically by hand slightly nudge the* [https://www.eham.net/reviews/view-product?id=6666 eHam.net Ciro Mazzoni Baby Loop Reviews]* [https://www.eham.net/reviews/view-product?id=6666 eHam.net Ciro Mazzoni Baby Loop Reviews A (''for some reason they have 2 sections for the same antenna'')]* [https://www.eham.net/reviews/view-product?id=9110 eHam.net Ciro Mazzoni Baby Loop Reviews]* [https://www.eham.net/reviews/view-product?id=9110 eHam.net Ciro Mazzoni Baby Loop Reviews B (''for some reason they have 2 sections for the same antenna'')]* [https://old.reddit.com/r/amateurradio/comments/l5ldoq/any_one_have_any_experience_with_the_ciro_mazzoni/ Reddit discussion related to Experience with the Baby Loop]There are currently no good youtube reviews or assembly videos at this time.
