I wanted to reach out to the community as I've had a few birdies in my ear telling me to throw bi-directional amplifiers on our 3650 gear to reach the FCC limit on omni-directional antennas. The gear we're thinking about here is a Redline AN100U which has 23dBm output.    I have heard some people tell me that ODFM and amplification is a terrible thing due to the carriers on the wave and timing. I have also heard people tell me there should be no problem with this if it is a "fast-switching" bi-directional amplifier. None of these people can really provide me literature or references to site their knowledge or show me actively working systems.    I know, based on what we've seen with a few acquisitions, that amps dirty pretty much everything but have gotten people through some difficult problems. We've got some amps on older DSSS equipment that doesn't work great but had enabled the previous owner of the company to house his radios in the hut at the base of the tower.    Any wizards out there that can shed some light on this?  -- Nick Huanca  GAW High-Speed Internet 619 Silver St, Front Bldg Agawam, MA 01001 [office] (877) 5-GET-GAW (877.543.8429) x214 [direct] (413) 203-4910 [mobile] (413) 570-0120 www.gaw.com Tell us how we did: www.gaw.com/survey --- PRIVACY AND CONFIDENTIALITY NOTICE:  This communication and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential, proprietary and/or legally privileged or protected information.  If you believe you have received this communication in error, please immediately reply to the sender and delete this message.  Any use, disclosure, retransmission, distribution, copying, or taking of any action based on this information by any person or entity other than the intended recipient is strictly prohibited and may be unlawful.  Because e-mail can be altered electronically, the integrity of this communication cannot be guaranteed. -------------------------------------------------------------------------------- WISPA Wants You!
