Review: Many new stations received with this antenna from deepest rural Gloucestershire ! - Good for shortwave great little indoor antenna very-very sensitive I wish I'd of bought one year's ago, I live in the countryside so I'm not so troubled by interference say a person living in a city, but I do have to turn off all of our other devices in our home, computers, wall chargers, mobile phones ect ect, ive listened to many many new station's it works great on my Roberts Shortwave SSB, MW, LW, FM Radio.

### ⭐⭐⭐⭐ Useful indoor/mobile antenna for SW
*by A***S on 23 April 2014*

I tried the 31MS on an Eton G3 (aka Grundig G3). To sum up the SW reception was improved, it's not a miracle worker however and the MW reception of my G3 was not enhanced. First some unpacking observations on the 31MS. The wire loop when hanging, is in the form of a square 44cm x 44cm hanging from a corner. This shape is maintained by a combination of a telescopic diagonal rod (rather like those found on any portable radio, extends from 12cm to 58cm) which locates on two knots on the wire forming two horizontal opposing corners of the square and the weight of the loop when hung from the middle of top wire (which forms forms a 3rd top corner) using either a supplied window sucker or alternative clip for other hanging possibilities. The remaining base corner of the square is a small plastic housing described in the instructions as the amplifier box, which has a small switch to select MW or SW and a socket to take the supplied 5m extension lead which allows you to be a reasonable distance from the hanging position. This loop is for indoor use only as none of the parts are weather proof. Fine perhaps if you are in dry conditions but don't leave outside hanging in a tree in case of an unexpected downpour. Battery power is being delivered to the box at the base of the loop. The extension has 3-conductor, 3.5mm jacks on both ends. This extension lead then plugs into the rectangular (7.5x2.5x1.5cm) battery powered tuning box which has an on-off switch with red power led and an antenna tuning thumbwheel. Actually on a quality check note, the on-off slide switch on mine was loose in the packaging and had to be clipped back on. The battery compartment could be tighter too. I also measured the current drawn at 13 mA, double that claimed in the instructions. Anyway, there is also a hole at one corner of this little box if you want to attach your own lanyard I guess but why? At the other end of the tuner box is a fixed wire about 40 cm long with another 3.5mm 3-conductor plug. From here the choice is yours. From here you can plug directly into your radio external antenna socket or use one of the two adapters supplied, both use a 3.5mm female socket to then give you either (a) two mini clips (white clip for attaching to the end of your radio antenna and black for earth) or (b) a short ferrite core for MW assistance. I want to comment on the ferrite adapter (with the loop switched to MW) because the ETON G3 has notoriously lacklustre MW performance. No detailed instructions are supplied with the 31ms antenna as to what you do with this core. The idea I believe is to move this core closely around your own radio and find both a position and an orientation that boosts the signal to your radios own internal ferrite core. Knowing where that is situated inside may help. I tried really hard with the ferrite core to find a position around all sides of the G3 to boost the MW reception to no avail. It made only a small improvement when the radio was rotated off optimum MW reception direction and none to worsen when rotated to its best orientation. The thumbwheel tuner made no difference. I should also say unsurprisingly it does nothing for air-band either. Just in case I tried the direct connection and using the clips to no effect for MW. But I did not buy either the G3 or this loop for MW so no worries just my results in case anyone was interested. The ferrite adapter may work better on other radios. SW is a different matter. Used the external 3.5mm antenna socket for direct connection to the tuner. After finding a signal or frequency of interest on the radio at night, carefully adjusting the tuning thumb wheel on the tuner box will effectively tune the square loop for the frequency you are on. Carefully hunt for the optimum wheel position. The signal meter will go full scale and the station becomes louder. This has to be redone as you move through the bands. This signal boost is very noticable, and when on a station often with an improvement in signal to noise. If off-station the noise is however also boosted. Unplugging the loop from the radio shows how poor the built in antenna on the radio is in comparison. With the loop more stations do come in to play with clearer speech which would not have been possible to listen to before. So I have to say this seems to work, probably not as much as a full external antenna set-up but this is for portable use after all. So from a SW point of view at least this kit is quite useful and easily outperforms a simple indoor long wire with a crocodile clip but you would expect that for the price. It's an indoor solution so compare with other indoor solutions. For MW users it may also prove useful but owing to the poor MW on my G3 I could not confirm that. The Degen 31MS is a neat bit of kit (compared to a DIY plain wire anyway) that packs away to a small size but some sort of drawstring bag would be a nice finishing touch to keep all the wires and other bits together.
