Great portable active antenna for portable radios
This is a great product for what it does and for its cost. It is a totally indoor active antenna system that works for both mw (am) signals from 520-1710 KHz and for sw signals from ~3.9-22 MHz. According to detailed technical reviews it works best above 9 MHz, but I have found very good amplification even as low as 5 MHz as well. Very little amplification is available above 22 MHz so this is not the product you want for CB radio activities for example. Power is supplied by two AAA batteries resulting in very low noise and with very stable and long duration operation. There is an on-off switch on the main control unit with a red LED light that readily indicates the status of your activities (so that you don't forget to turn it off!). There is also an analog switch on the opposite side of the control unit from the power switch that needs adjustment as you change operating frequencies on your radio. It is a bit finicky to operate and a fairly small wheel to slowly turn, but it can be...

Kaito KA33
Works as advertised for SW, so so on AM(MW). I bought this for SW reception and it is a jewel at pulling in stations that were ever so faint before. It took a little while, trial and error, to find the best place for antenna to hang. Once I found a place for the antenna stations came in much clearer. I was never able to pick up Radio Japan clearly before, now it comes in very clear. The tuning on the antenna is very sensitive and took a little getting used to but I found that once slowly tuned within a band I didn't have to re-tune until I switched SW bands. The only thing I really would like to see in the kit would be a complete manual and adapter for PAL antenna connector. The instructions are on the back of the box. I ended up cutting the clips off and soldering the ends to the PAL connector that came with my CCRANE CCRADIO-SW. Once I did that reception improved due to the fact that the ground clip kept slipping off connection. I am very pleased with SW reception. For AM I tried...

I tested the Kaito KA33 antenna using my new Kaito KA1102 radio.
Yes, the antenna did give some improvement in reception for both SW and MW(AM) broadcasts. However, potential buyers new to SW radio should understand that it amplifies interference along with weak radio signals. But on fairly clean weak signals it is really helpful.It should also be noted that my home location is not favorable for DX-ing - either SW or MW(AM) radio. In places like Mexico City however, this little antenna would most certainly excel - even when used with cheap SW or MW radios. My Kaito radio, when used with this antenna, compares unexpectedly well with my 15 pound Grundig Satellit 800 - when using only the Grundig's built-in antenna's - and using headphones on both radios.Lastly, the antenna comes with several small pieces and perhaps should be kept together in the original box. For me this would take up too much room in my suitcase. I'll probably take the radio and leave the antenna at home when going on short trips.
