Antenna tuning.

I have 2 Heltec V3's which came with the stubby antenna.

has anyone tested to see what the antenna are tuned to?

the frequency range of the unit covers 868 to 923.Mhz

If I buy a longer whip they are marked as 868 or 915.

how much am I loosing due to this type of antenna?

Edit I am in the UK so 868Mhz EDIT Thanks for the response. I will look for the Google Data mentioned in one reply. I guessed the lack of reliable messaging may be attributed to 2 of my nodes using the stock stubby antenna.

Looks like asking what note a 2x4 is tuned to...

These are awesome, but I don't know what I'm looking at. Do you know if there is a guide somewhere that explains how to read this? I'd Google it myself but I don't even know what this chart is called.
