[TowerTalk] Question on Lightning Protection Devices, Polyphaser, etc.

[Steve Norris]

Have two general questions/assumptions on use of polyphaser devices at 
frequencies OTHER than the design bands.

(1)  I would assume that a unit's inherent lightning protection for the coax 
run would be "intact", regardless of the frequency design of a device.  It 
just wouldn't necessarily be useable for transmitting or receiving at none 
design frequencies.  That being said:

(2)  I would also assume that a device designed for HF frequencies WOULD NOT 
be useable for higher bands VHF/UHF/SHF frequencies.  I wouldn't try that. 
However, I have no idea whether units designed for the higher frequencies 
(i.e. cellular bands at 800mhz and up), could safely be used on "lower" 
frequency HF/VHF bands.  The reason for the questions is the cheap 
availability of some "very robust commercial devices (Polyphaser) removed 
from cellular service.

I would STILL use devices at the house/shack entry that are designed for the 
correct bands.  But, I was hoping to add some of these bulkhead polyphaser 
units at the tower/antennas, for additional protection.  Comments?
