<br>
The major difference here to what was suggested above is that<br>
Pirate<br>
Cat hosted its antenna in many many different places over the<br>
years.<br>
We moved it every 3 months or so. And 95% of the membership<br>
didn't<br>
know where it was.<br>
<br>
My point was to ask the question WHY put up the antenna at<br>
all.<br>
<br>
The return on investment for putting up an antenna --<br>
particularly,<br>
one physically located at the locus of control as opposed to<br>
offsite<br>
somewhere like in a van or something -- is pretty abysmal.<br>
Listenership to the airwaves continues to drop.<br>
<br>
If you decided to jam some corporate radio station, you'd be<br>
implicating Sudo Room and the feds would come down on it<br>
sooner or<br>
later.<br>
<br>
If you just wanted to squat some frequency in the lower band,<br>
you'd<br>
have an abysmal listenership at the cost of the power of<br>
operating the<br>
antenna.<br>
<br>
It's just not that compelling an exercise for the amount of<br>
risk.<br>
Not for me, anyway. I guess a lot of people still feel that<br>
the<br>
airwaves are somehow inherently exciting.<br>
