Bandpass Filter Q & A Question: Why do I need a Hyperlink Ultra High Q band pass filter Answers: To reduce interference thus improving radio reception. To increase performance of co-located equipment. Question: What is interference and why do I want to eliminate it Answers: Interference is caused by transmission sources near the band you are transmitting on. It can be identified by signal strength and frequency. Unwanted transmissions, interference, may confuse your receiver or cover up the signal you are trying to receive. Question: How do the Hyperlink Ultra High Q band pass filters work Answers: The filter will only pass the frequency range you are transmitting or receiving and reduce the interference of signals outside your band. The filter will NOT reduce interference within your frequency band caused by other signals or users within the same band. Question: What is meant by frequency band filtering Answers: The passing of frequency band while rejecting all other frequency bands. The protection against signals outside your band such as cellular. rd L-com, Inc. 50 High St., West Mill, 3 Floor, Suite 30 North Andover, MA 01845 www.L-com.com E-mail: sales L-com.com Phone: 1-800-343-1455 Fax: 1-978-689-9484 L-com, Inc.
