Cable TV In-Line Coaxial Surge Protector
Any reason this device couldn't be used with a cable modem or a satellite television system?
This may block the return path that some digital cable systems need to operate. It will also block the voltage for the satellite dish to operate.

What's the frequency range?
The previous question on the loss gives an answer for loss to 1500 MHz, but other sites list this same part (including PE model) as covering 5-2300 MHz.

How does this device shunt a surge with no apparent ground connection?
One would think that surge protection would require a heavy ground in order to carry the energy of the surge away from the device and the equipment it is protecting. How is protection achieved?
Surge Protectors of this type use a metal-oxide varistor (MOV). Varistors are often used to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when triggered, they will shunt the current created by the high voltage away from sensitive components.
