Hello, we are Yanks traveling in NZ by yacht. To have internet access we have a Vodafone GPRS card by Option (doesn't support 3G) inserted into the PCMCIA slot of our Compaq laptop. We recently upgraded our TV to a Sharp LCD. It is powered from our 110 inverter. It's signal is fed by coax from an (12 volt) amplified antenna on a gimballed mount on the backstay. When the GPRS card transmits data, it causes dreadful interference on the TV. Is there a remedy for this? Sorry, I looked but couldn't find anything that addressed a problem like this in your archives.
Yes, get an amplified antenna that has a filter for the GSM band in it. Its a known problem with amplified antennas when they are near a much stronger transmission.
Thank you, richms. Most of the amplified antennas don't have a spec sheets I can read to assure me that the product would solve my issues. I have been scouring the internet for a filter I could put in line with my coax in to the TV but I can't find anyone who supplies such a thing. I could only find filters to filter out low interference or certain segments of the TV bands. Have written to several vendors for leads and no one can help me yet. Suggestions, please?
Wow, thanks for that! I guess I'll be hunting for a new amplified antenna. Another question: why didn't this interference happen with my old CRT television??? And even now with the LCD, it varies from channel to channel (1 is usually OK but 3 is rarely OK) but sometimes it's all bad?? We've played with moving the GPRS antenna a bit but its cable is too short to make much difference. So it wouldn't do me any good to get a remote GPRS antenna--like a magmount type to mount outdoors? In fact, might make things worse? Thanks so much for your guidance.
