Hello- I have for sale a Bird wattmeter element # 2500-H, rated 2500 watts 2-30 Mhz. This element was found in a sealed plastic bag in some NASA surplus.If someone desires I can open it and test it to the 150 watt level in my meter. It is excess to my needs. Sell for 50.00 plus shipping. Thanks, Byron WA5THJ.
