Hello,
I've read this http://www.google.pt/url?sa=t&rct=j&q=&esrc=s&source=web&...
Can you please tell me how can I use the bird 43 on 23cm band? I need a good precise swr meter for 70cm and 23cm band. However from specs bird 43 can't go to 23cm, only limited to 1000MHz.
Thank you.
Best regards,
João Fonseca
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 %.

Hello Joao, CR7AJC
Not true ! the Bird Company supply upon request measuring elements for the frequency band 1100 to 1800 MHz for power to be measured between 1 watt to 500 watt and I have tree of those measuring elements one is for maximum 1 watt, the other for maximum 25 watt and the last one is for maximum 500 watt.
The only problem is that they must be expecially manufactured upon customer order and so they are very costly ! !
