How to configure Radio Mobile for propagation simulation?

Hi,

I’d like to create a propagation simulation for my antenna (a Lorix ONE) and am using the free online Radio Mobile website but am unsure how to configure it properly. So far I have the following

I think I’ve managed to pull the relevant info from the Lorix ONE website in terms of TX power and RX threshold, but I’m unsure about the TX/RX line loss and whether any of the other params need to change from the defaults? How should one work these out? (I’m using 902 MHz for Frequency due to free limitations, but should it be a big difference than 868?)

Any guidance appreciated.

Many thanks

Matt
