Indoor TV Antenna
I'm wondering if the $20 or $30 indoor TV antenna's are any better than the $10. I'm trying to get a channel below 13. The bunny ears on my $10 job are 3' long. The bunny ears on the more expensive...

When you say "Channel below 13" are you talking broadcast channel or display channel, they are occasionally the same but not often.
IE: Channel 2 (Detroit) broadcasts on 7
7 (Detroit) on 41
I won't say which antenna is better, sometimes the lower cost one wins out, Generally for lower frequencies longer is better, but INDOOR antennas, depending on you use of language either SUCK (Quality of recption wise) or do not SUCK (in signals well).
Suggestion: Find the frequency, not the channel (many converters give you both or you can go to any of the "US TV CHANNEL" links on the web)
Do the arithmetic (75/(Frequency in MHz)
Adjust each "Ear" to that length, and lay 'em flat with 75 Ohm cable and you should be right close to as good as an indoor antenna gets.
Lamda (Wavelength) is 300/F(MHz) so the figure I gave you was a quarter wave. You have just made a half wave (2 quarters) Dipole, native impedeance of a half wave flat top dipole is 72-75 Ohms (Same as your coax) so you good)
