In my metropolitan Kansas area, with my rabbit ears, I get an ABC affiliate, an NBC affiliate, a CBS affiliate, a Fox affiliate, a PBS channel, and one fair independent. The problem is that on the local broadcast channels for about 60% of the actual broadcast hours they've dropped the network feed to insert "paid commercial announcements" on all of them (I can also get 4 or 5 24-hour-per-day "religious programming" independent channels, but don't watch them much since they're 100% pca.)

Clearwater FL may be a bit different, and of course it depends what kind(s) of programming may be of interest.

If she's in a "modern" appartment, in order to prevent a clutter of rooftop antennas some apartment complexes install one antenna and provide an antenna outlet in each apartment, often included in the rent. If the "community connection" is cable or dish, there may be a monthly charge for using it. She'd need info from the particular landlord to find if something of this sort is available.

The situation with respect to purchasing a "throwaway" TV likely is a bit different in most US places than she may be accustomed to in the UK. It generally is assumed that one will appear at a retail storefront outlet to make such purchases. For an item this small, delivery is unlikely to be included. Clearwater doesn't appear to be a very large city, so with luck the apartment might be within walking distance of an appropriate store, and a 2-wheeled laundry/shopping cart might make fairly easy transport of a small TV for a moderate walking distance.

Perhaps clearwater tv freak might be able to indicate whether taxi and/or bus public transportation is available/convenient in Clearwater, and what "big box" stores would be likely to have something suitable?
