Fixed value “in line” CoAx attenuator
Male Co-Ax to Female Co-Ax (also available in F connector)
Available in 6dB and 12dB values
5 to 1000 MHz
See article on attenuators
Attenuators can be useful in discovering if you have sufficient signal to use a splitter (as opposed to an amplifier). If your signal is still fine with one of these inline (see through loss of splitters) a splitter will be fine, an amplifier is not required.
NOTE : purchasing a 6db and a 12dB fixed value attenuator gives the option of 6db or 12dB or 18dB total attenuation, this is an alternative to a variable attenuator.
