Hi Richard,

The real way to have a "really big signal" is to have a "really big 
antenna". You get tons more bang out of a really good antenna than a big 
amp. Sure the kilowatt helps too but the first thing to have is the antenna. 
Many people subscribe to the 50/50 rule where you spend half your station 
budget on antennas and half on the rigs. My own experience is that you 
should actually put more into your antenna than your rigs.

Ask yourself where you want to have a big signal and then build the right 
antenna for it. For example if you want to kick butt on 80/75 for DX, then 
put up a four square. This antenna however doesn't put a big signal straight 
up. If you want a big signal for the locals (NVIS propagation), a low dipole 
is the way to do it. The same holds true for the higher bands. A stack of 4 
element StepIRs on a rotating tower (or ring rotors) will give you the 
ability to adjust the launch angle to get you a bigger signal for DX than 
just a high antenna. There are times at my station when a low (50 foot high) 
antenna does better than the high (90 foot high) antenna. The stack lets you 
optimize the angle you're working as well as the direction. See the HFTA 
program for more information on that.

A station who invests in the optimum antenna will always have a big signal 
regardless of power. 10 db of antenna gain works on both transmit and 
receive so it's actually better than having 10 db more output.

Good luck and 73,

Jerry, K0TV
