FF10
Hints for a safe disassembly of the Velcro mounting:
The Velcro supplied with the filter has an astonishingly good ad-
hesive strength. You may therefore run the risk of loosening the
adhesion of the Velcro from the meter or filter instead of discon-
necting the two Velcro pieces when trying to dismount the filter.
To avoid this, please do not pull apart the filter and the meter,
but carefully fold the filter towards the front of the meter so as to
loosen the Velcro pieces bit by bit. For an easier disassembly,
we have minimized the sizes of the Velcro pieces.
6. Optionally available: "Two-hand solution"
with connecting cable
For this solution, the UBB antenna needs to be tightly connected
to the FF10, and this filter/antenna combination then attached to
the meter with a 1m coaxial cable. The fees for this modification
kit and the corresponding assembly in our factory can be found
on our homepage.
How the Filter Works
The filter only allows the selected frequency band to pass
through, and suppresses all other frequencies.
For all filter settings – including "LP 480 MHz" and "broadband"
(which is the bypass position at which all frequencies of the an-
tenna pass) – the frequency response is compensated, that is,
the occurring insertion loss is compensated by a frequency-
specific amplification.
