I recently installed a Polyphser IS-T1 on my DSL line. It cut the bandwidth from about 1.4 MBps to 200 KBps, so I returned it. Can anyone suggest a lightning arrestor for DSL lines that does work and doesn't interfere with the digital signal? 73, Barry W2UP -- Barry Kutner, W2UP Internet: w2up@mindspring.com Newtown, PA Frankford Radio Club
