I'm wondering if I should try and use this for aligning my antenna. It claims to work on digital signals as well. I don't have the power supply, but it does take batteries, and I"m sure I can work out a 12V supply if that doesn't work. Is this meter worth messing with or should I move on and try and sell it to a contractor that can actually use it for install work/testing?
Thanks for any info you can provide.
I just visited their site and found an even better fit:
NiMH Battery: 9.6V 2200 NiMH Tx Batteries for NT8JY Futaba 4NBL/BF/BP
Your Price: $16.99
Product ID # 776
Part Number: RA-HAA8R1HT22
I also found packs of 9.6 volt batteries for $10 but with a lower charge capacity, 700mAH, which may be fine for you but I have to use mine all day and it was worth getting larger capacity batteries for the $10 difference.
The BTPDA-4 measures down to -45dBmV, whereas the BTPTD-2 only measures down to -35dBmV, so it is a very good meter for detecting and evaluating weak signals. You won't make enough selling it to buy another meter so if you need it, you might as well keep it.
