João,
According to Bird, the 43 is good to 2.7 GHz with the correct elements:

I have a Bird 10k element, 10 watts, 1.1-1.8 GHz, however I did not see it on their list of current accessories. You can find them on eBay. Coaxial Dynamics sells elements which cover this range which should be usable with the Bird 43:

I assume you have a standard 400-1000 MHz element. Depending on your needs, it MAY be accurate enough. Twenty years ago, I compared the 10c (400-1000MHz) with the 10k on 23 cm, and they agreed within about 5 %.
73s,
