-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Yes, if your erp goes too high, you need a license. I can't remember what the legal limit is nowadays - I think it's 250mW. erp is measured at the output from the Ae. Ireasing the amplification often only affects transmit power. Increasing the db gain of the Ae increases transmit and receive. So it's often better to lower the transmit power and use a better Ae in order to stay within the legal limits. jon On Friday 25 Jul 2003 8:02 pm, Jonathan Melhuish wrote: > On Wednesday 23 July 2003 09:06, Jon Lawrence wrote: > > Hi, > > For ideas of pricing for wireless antenna's take a look at > > http://websites.uk-plc.net/Shop_Online_for_Wireless_Products/ > > By using the correct antenna match with the appropriate amp, we've > > comfortably reached 20+ miles with a point to point link.
