I've not had any problems with the UHF circular loop
that comes with standard rabbit ears. The only problem
I've had is with VHF channels on the dipole. I need
a weatherproof version of my RS rabbit ears.
Unfortunately, ABC is Channel 7 here in Tyler, TX.

Now that the FCC has given a green light to whitespace device
deployments (particularly those that rely solely on spectrum-sensing
technology), you may find you need a better antenna than a simple
loop, bowtie or coat hanger.

For those of you who are not following the issue, a quote in this
week's TV Technology pretty much sums it up:

"MSTV (Maximum Service Television) told the Commission Oct 31 that the
least the FCC could do is subject the devices to rigorous testing
beforehand and ensure fair and reliable tests to prevent interference
to DTV. In a filing, MSTV also attacked the FCC proposal that a
device should be able to detect signals as low as -114 dBm, a level
MSTV equated with setting a smoke detector to only be able to detect a
raging fire."

Whitespace devices will also cause great harm to wireless microphones,
particularly older models.
