[TowerTalk] Chicken Wire Ground Screen

I really, really wish people would stop making generalities like that 
regarding amps versus antennas.  Every situation is different, and many 
don't even come close to supporting that statement.  Here are two 
hypothetical examples:

1.  Somebody has a 50 foot tree in the back yard of his suburban lot 
with a couple of dipoles hung from it, oriented in different directions 
and fed with 100 watts on 40m through 15m via a tuner.  He's going to 
hear most stuff just fine, and the $800 bucks he spends on a good used 
amplifier is going to be far more cost effective for making contacts 
than whatever he would have to spend to put up a tower, tribander, and a 
shorty-40.  Less visual impact on the neighborhood as well.

2.  Somebody on a large acreage has a decent vertical antenna capable of 
tuning both 160m and 80m with a switchable L-network.  He can spend a 
few hundred dollars for a used amp, lay out a few BOGs or build a 
rotatable loop (pennant, K9AY, etc) for better receive, and end up with 
a 10 db signal versus the maybe 5 db stronger signal he'd get from 
spending the same amount of money on a 4-square or any reasonable 
alternative.

I'm not knocking the advantages of better antennas, and if you check my 
web site you'll see that I just sunk a hefty chunk of money into mine 
within the last 18 months, but I think the cost effectiveness versus an 
amp is an exaggerated generality.
