Comment:

 This is something that looks not too difficult to implement, although it
 needs a database schema update to store the LNA setting.

 I have done comparative testing with "LNA off" and "LNA on" with two
 different DVB-T2 tuners, a MyGica T230 USB stick and a Digital Devices
 PCIe card.
 On both tuners there is no difference whatsoever between "LNA off" and
 "LNA on" as shown in the Signal/Noise and Signal Strength values in the
 mythtv-setup SCANNING page.

 The question is whether implementing this will make a difference for
 anybody.
 If there are tuners who are documented to have an LNA then please add them
 to this ticket.
 For those willing to test their DVB-T2 tuner, the patch that I used to
 test this, 20191217-lna-on-off.patch is attached.
