Can anyone tell me about them?? Are they any better or worse than wire
antenna?? Thanks for any comments about this Steve


I have a Dymek DA100D active antenna I've used for years, indoors, on
an NRD-525 receiver. It pulls in stations, but not as well as a full
size outdoor wire antenna -- the Dymek is about 2 S-units down on a
given frequency, compared to an Alpha Delta 1/4 wave swl sloper.

On the other hand, the Dymek is a heck of a lot smaller than a big
outdoor wire; it has about a 5-foot whip on it.

I do like the Dymek indoors, as it allows safe listening when there
are thunderstorms about. But a simple wire, thrown out the window, may
receive as well or better, and be a lot cheaper.

Also, in reference to another post, I'm about a mile from a 50,000
watt AM station at 550 khz and it does not seem to cause a problem
with the Dymek active antenna.
