In fact, none of the people we interviewed even mentioned it until we prompted them. For most shoppers, a good tabletop radio should be as pleasing to touch as it is to look at. Solid tuning and good ergonomics are a major priority.Interviewees also quite frequently mentioned that a variety of finish options would be preferable, though not essential. By a huge margin, the feature that most people mentioned first was design, with the terms “retro” and “executive styling” popping up time and again. I also find his use of an ad-hoc “felt-clutch” to be very ingenious. In fact, Alex PY1AHD himself and his coworkers have been working on several possible solutions:Īnd others have devised similar approaches, also for the Alexloop:įor the use I intend, the approach by K2MVR seems to be the simplest and easiest to implement. Since I already own an Alexloop it would be great if I could just add a motor operated device specially designed for the Alexloop, that could be attached to its variable capacitor and allow it to be tuned from a remote location. However, Chris Käferlein DK5CZ has been SK since 2005 and his antennas are no longer in production. I was hoping to also be able to consider the DK5CZ AMA remotely tuned magnetic loops (Jean Devoldere ON4UN, the “guru” of low band DXing, had one in his garden!). Unfortunately, with the exception of the G4TPH “ML40HP MKII” and the Czech MLAT-T all others cannot be considered as “portable”, and the MLAT-T does not operate in the high-bands (its smaller version, the BTV MLA-M V.5, which with the aid of jumpers is listed as able to tune 10m – 80m, can only be manually tuned.
However, I decided to start by surveying what would be readily made and commercially available. Here is the list I came up with for currently commercially available remotely tuned HF magnetic loops:īands: 15m – 40m (w/10 rails) 10m – 12m (w/7 rails)
#REMOTE ANTENNA TUNER REVIEWS MANUAL#
Some are manual and some automatic some require a cord and some are wireless. Many possible solutions have been proposed for remotely tuning different magnetic loops. The solution would be a remotely tuned magnetic loop. In other words: I hate to have to get outside or open the car window every time I need to tune the loop. Hence, it would be nice if I could minimize any exposure to the cold air outside the vehicle.
#REMOTE ANTENNA TUNER REVIEWS PORTABLE#
However, as I grow older, I tend to prefer operating outdoors “car-portable”: with portable equipment but from inside the car – my faithful (and heated…) Jeep Liberty RGB. Also, in the past, during the winter months, I did not mind operating outdoors in the cold.
Since then, this antenna has served me well as a travel companion, allowing me to operate from several continents both indoors and outdoors, from summits, islands or parks and even from my small sailboat. This and further testing convinced me that the principle worked, and I wrote to Alex PY1AHD to place an order for a travel Walkman PY1AHD Alexloop. However, the first time I used it in 15m I made an SSB QRP contact Ottawa to Greece. This crude “VA3PCJ Hoola-Loop” would tune 15m to 80m (although for 80m its efficiency was dismal). Here it is (click on the image for further pics): Hence, I built my own small magnetic loop prototype with a Hoola-Hoop, a piece of braided grounding strap, a variable capacitor from eBay and some PVC pipe material. Three years ago I considered acquiring an Alexloop PH1AHD as a travel antenna, but before placing an order I wanted to convince myself that such a device would work.
