Great additon for a Mag Loop to make tuning easy! Time Owned: 0 to 3 months.
I purchased the SR-705 knob replacement for my mag loop antenna and what a sweet device. Makes tuning a breeze and a joy to use. I asked AA for some advice and Steven suggested the SR-705 as a solution - and it certainly is! You need to get this if you have a mag loop with a 1//4 inch shaft on the capacitor. Highly recommend!

Perfect accessory Time Owned: 0 to 3 months.
I just got this tuning knob and can't say it better than WA7JFO. I use the enhancement loops so I can concentrate on 40M and 20M. This makes it so easy to nail the lowest SWR. And no effect from touching the knob. Outstanding invention and I highly recommend it to anyone using Alpha Antenna's magnetic loop antennas. Steve provided great customer service and advice. Great company and product. I'll never go back to low dipoles again! Easy tuning without a tuner and multiple bands in a small antenna with great performance. I wish I had found this 30 years ago!

SR-705 is all that, and a low SWR. Time Owned: 0 to 3 months.
This is the exact accessory you need to overcome the twitchy tuning of a mag-loop antenna. The execution is simple and light which makes it convenient and reliable. Thanks Alpha antennas!

15 seconds of use changed everything Time Owned: 0 to 3 months.
I knew this SR705 knob was something special within 15 seconds of using it on my Icom AL705 Antenna Loop. It’s also clear that it could be pushed right onto any 1/4 inch shaft.
Hand capacitance? 95% gone!
Fine tuning? Here to stay!
You can tell an engineer with a heart for a positive end user experience designed this knob when you hold it for the first time. It really is a work of high functioning art.
