It is usually impossible to tell without trying it. In most cases the answer is to use a pre-amp.
No web site (or person on this forum) can tell you what you need in your location to get the results you are looking for. It is just an educated guess. There are numerous variables.
- Type/quality of coax.
- Pre-amp or not.
- Trees
- Antenna. You definately need a VHF rated antenna, but you are lucky that FOX is High VHF rather than Low VHF.
- Height above ground.
- How well your antenna is aimed.
There are two ends of the scale in selecting equipment. You can start at the bottom and keep upgrading until you get reasonable results, or you can go high end from the start (which in some cases isn't good enough). I took the low to high road and wasted money along the way, but learned a lot in the process.
The one thing you should not skimp on is the cable and connectors. It is a relatively low cost item that is normally not easy to change once installed. Have as few splices as possible, and don't have a lot of excess.
