(meteorobs) Newbie - Antenna and transmitter selection -ADDENDUN

[stange34 at sbcglobal.net]

Addendum to my response:

Be aware that FM antennas usually have an impedence of 300 ohms, (sometimes 
75 ohm adapters are included). You must MATCH the antenna impedence to the 
recievers antenna input impedence. Ham & Radio suppliers have adapters 
called baluns etc. Be sure and do this matching for optimum operation of 
your station.
