Those signals may appear good enough to you, but the Explora is more sensitive and lots of forum experience says otherwise for longer term usage, and our findings are on a parallel with what MC has posted about it before.
I have nearly 40 years of on and off experience, I am sure that the "slightly" better values suggested below make enough of a difference.
The best way to test that we regularly present Forumites recommend;
To test tuner 2 always start a recording first (recording the same channel as the one it's suggested you view live for each tuner 1 test).
Test channel 262 (vertical polarisation), and then 405 (horizontal polarisation) for tuners 1 & 2. For tuner 3 just take the readings.
Strength 80%+ on both horizontal & vertical polarities on tuner 1 & 2, 65 to 70%+ on tuner 3. Quality for all tuner results on 90%+, perhaps 1 or 2% less would do.
