BIRD WATTMETER ELEMENT (SLUG) TYPE 25B FOR BIRD MODEL 43 TYPE OF WATTMETER. Measures 25 watts full scale from 50 - 125 MHz with great accuracy. Covers above and below this range with GOOD accuracy. Added resistors will let this slug handle much more power - there was a recent article in QST magazine on this mod. With some simple mod's, they can be calibrated for any range or power: http://www.hayseed.net/~jpk5lad/BIRD%20Slugs/birdslug1.htm Bird publishes charts that show the deviation from the guaranteed range on many elements. The element works and it is in LIKE NEW condition. (please look at our rules and privacy policy) |
