30 dB attenuator on eBay and thought that I might mention it to my
fellow hams as a possibility for a very nice dummy load. Some of you
may not know that any large, well designed attenuator (e.g. greater than
20 dB attenuation) makes a pretty darned good dummy load. In fact, I
have a 30 dB 100W Bird that I am using myself as a dummy load. Fairly
compact, no oil, flat to 2 GHz - what is not to like.<br>
<br>
The eBay item # is 250819745325.<br>
<br>
By the way, I have no connection with this item or with the seller. I
did check with the shop that is selling it and they did a quick check
and it does read 50 ohms on the input connector so it looks like the
damage to the output would not affect it's suitability as a load.<br><br>Another note: the 75W power rating (or xx power rating on any Bird attenuator or load) is a key down, 100% duty cycle rating. The ratings for lower duty cycles (e.g. CW at 50%, SSB at ?? 25%) are proportionally larger. There is a limit but it is apparently quite high.<br>
