The HotSpot wouldn't be if we had to use high gain, small VBW antennas, the beam would hit way to far out.
Microwaves, are just little bit different animal though, aren't they ? ;) ---------- Original Message ---------------------------------- From: "Kevin Proctor" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Wed, 3 Sep 2003 13:46:29 -0600 >Ah, but the narrow beamwidth helps eliminate reception of signals that >might otherwise interfere. > >A higher gain antenna is generally preferable in the RF world to an amp. >Any active electronic circuit will introduce noise of it's own. >Antennas are passive components and therefore introduce no new noise >into the signal.
