Hello meteoestarreja,
thank you for your very informative and detailed feedback. I appreciate that you took the time to share your knowledge.
So taking your answers into account we have to confess, that it's more or less random how the frequency of the resonator is tuned and shifts with voltage in addition to the sensitivity of the receiver.
In summing up the best would be to match transmitters and receivers.
Concerning the topic with the bad reception when using a wire this should also be investigated. Taking into account the free space attenuation i have path loss of 63dB ideally bridging 100m and in 100m RG58 wire I have a path loss of 40dB. So this must mainly be a effect of the connectors.
Back to my question - the transmitter I linked should work basically (if it is tuned right), or does anybody have some constraints?
Well I will have to get a variety of different transmitter types, build a test setup with adjustable transmitter supply voltage, motivate my friends
and do some measurements of output power and frequency.
Maybe I can do this around Christmas time
Meanwhile I will try to get along with the current situation, because it might be ok, when aligning the antennas properly. But nevertheless I'm taken by that topic.
