Yes. Get your antenna as far above your setup as possible.

Looks like this guy is going to fit right in. He has managed to combine his profession (ambulance chasing) with his hobby (radio). He will be happy to find that all too many of the denizens here share his hobby and have his profession as their hobby too. This is going to give much more milage to the "Can I order a pizza if I refuse to pay the delivery boy" questions. My understanding of amateur radio is that 70 years ago, the old farts just wanted to sit around and talk about radio theory while the young Turks wanted to build radios and transmit with them (using CW even). Now we seem to be at a stage in our history where the old farts want to sit around and discuss radio rules and regs while the young Turks want to build radios and transmit. Things haven't changed much, but I think they have changed for the worse. -- Julian Macassey, n6are julian@bongo.info.com ucla-an!denwa!bongo!julian N6ARE@N6YN (Packet Radio) n6are.ampr.org [44.16.0.81] voice (213) 653-4495 ------------------------------ End of Packet-Radio Digest ******************************
