Calculation of range of coverage:
- cascade with distribution by floors
- example for sub distribution in longer installations
(in this case you need to use 17/2A instead of the LNB’s)

Isolation of the 17/8K, for calculation purposes without consideration
of the LNB’s
)
Together with the 25dB of the LNB’s at best there will be arising
approx. 24dB isolation. If you add two 17/2AR and one
17ZR in a longer installation (see 6.2),
the will decrease to worst case)
=> That’s just enough to operate.
