- TEST - BIRD 2500 WATT DUMMY LOAD
- MAKE A REASONABLE OFFER - - MAKE A REASONABLE OFFER
-
I have available for sale a BIRD 2500 watt dummy load, model 8890-300. This is rated at 2500 watts CONTINUOUS DUTY - - no time limit at 2500 watts. It currently has an N female connector on the load, but I can change that to a UHF(SO-239) or an HN or even an LC if you prefer. The load's SWR is under 1.1 at 1 GHz, and under 1.3 at 2.4 GHZ. It has the Shipping plug installed. The Breather plug is included, and attached to the Shipping plug with a short chain.
-
My asking price is $1200 plus shipping, or I can deliver it to you at any local hamfest. This is very heavy, almost 60 pounds, so shipping will be expensive. I travel to many hamfests in the mid-Atlantic area, so delivery is possible to save the shipping cost.

More pictures available.
