Locked Kaito KA-31 Shortwave Active Loop Antenna


msznh
 

I'm thinking of buying a Kaito KA-31 shortwave active loop antenna but
before I do I thought I'd ask if anyone has any experience with this
antenna and if so, would you be good enough to share your opinions on
it?

Thanks,

Tom

Hi Tom

These antennas are available under a variety of names and, from online
checks, the KA31 looks to be equivalent to the Degen DE31, covering shortwave
3.90MHz to 22MHz.

The DE31 has been superseded by the DE31MS which has the same shortwave
coverage but also covers Medium wave broadcast. The Kaito equivalent of this
looks to be the KA33.

You'll find discussion of the DE31MS in the archives here, as well as an
internal photo in the photos section.

I don't know what price you've seen the KA31 at but when I checked online
the Kaito versions seem to be selling for approx twice the price of the Degen
equivalents. A KA33 from a US seller was $49.99, a DE31MS on ebay, direct from
China was $22.90.

I bought one direct from China following the discussions here and it arrived
quickly.
One item missing from mine was the suction cup for window mounting. When I
commented I was told that was no longer supplied and that the advertising
literature would be changed.
I was quite surprised, it is a fairly fundamental part of the mounting kit
after all, but no real problem as it's a cheap enough item from any hardware
store.
The online literature doesn't look to have changed so perhaps they just
didn't want the extra expense of posting one, which I can understand.
So no big deal but thought I'd mention it just in case it is a universal
change.

In use it's a bit fiddly, tuning is very sharp on medium wave, so a bit of a
pain tuning around the band, although not so bad on shortwave, but very good
value at $23, and it works ok.
I personally wouldn't have wanted to pay $50 but take a look at the archives
and see what others thought of it.
If I was travelling a lot, or had problems putting up other antennas, I
would probably value it more but I bought mine mainly as a curiosity and just to
have a play with it.
Having said that, I'm not implying it's "just a toy", as a general purpose
antenna, within it's frequency range, it does a reasonable job.

I have both the SW an AM loops, I bought them for 16,9$ from tku-china on ebay ..

They are worth the money, ie the sw loop is better than a self made 85cm loop (without ampli ..).

The MW loop is a bit difficult to handle, since you need to put the small ferrite on the radio, and it is too small and light to remain there ...

I agree, but I fugure that is why they invented electrical tape... or
maybe use duct tape... or whatever works. Photographers gaffers tape
is a good choice because it comes off without leaving residue. Maybe
masking or blue painter's tape...

Just MY take... /// Richar5ds ///

Oh yes!
You must be a Great genius, because I also was thinking about trying to use some kind of tepe to keep the small thing on the radio receiver... This happened a few hours ago, I mean immediatelly reading those lines of the poor man without a way to use it in a proper way....
(Just to keep up a nice smile.)
