Thanks! That's exactly what was needed.
AntennaWeb scares a lot of people (needlessly, IMO) because it's very conservative. TVFool is a much more precise tool, which is why most folks here prefer it. You should be able to receive every major station in the Orlando market reliably, and then some, with the components suggested below.
As for expense, here's some good news: Perhaps $200 for components/materials and $100-$200 for professional installation should get you an antenna system that will provide years of reliable reception.
All of the suggestions below should be ordered online; only a few folks have an antenna shop/professional installer nearby who deal in quality equipment like this. Here's a list of vendors.
For best prices and decent service, stick with Warren, Stark, Summit Source or Solid Signal.
On to the specifics:
* Winegard HD-7696P antenna for channels 7-69
* Winegard HDP-269 antenna pre-amp
If you'll be doing the work yourself:
* Any good quality, balanced, three-way splitter
* Mast, mount, RG-6 coaxial cable, coax connectors, grounding equipment, cable stand-offs, etc.This
is a good, comprehensive DIY guide on antenna installations.
If you plan on hiring a professional to install the system, ask if he/she can furnish the accessory components. They may be less expensive this way, even with the contractor's markup, since shipping can be steep on heavy/bulky items such as mount, masting and bulk cable.
