Antennas exposed lengths differ!
 

I bought an antenna set Futaba FP08A17301 (400 mm) as a replacement for the original for a receiver F7008SB. This, because I want to install the RX in my Vario Lama (anywhere lots of metal), and I want to locate the antennas as far as possible from each other. When I measured the exposed ends (without screen), I noticed that the ends of the 400 mm antennas were 2 mm longer compared to the original F7008SB antennas. I have a total of three F7008SB's who all have the same length (shorter). Is there any reason for this difference? Maybe this antenna is not appropriate for R7008SB?

Any of the Futaba 2.4 GHz receiver antennas will work correctly. Some may have minor variances to account for tuning lengths in the coaxial cable.
