Do I need a preamp.
The first thing you need is a VHF antenna aimed at CHCH. Y5-7-13, Y10-7-13, or YA1713 are good choices.

Add the VHF antenna to the DB-8 with a channel 11 Jointenna.

The preamp with the least likelihood of overload is the HDP-269 but it's gain is marginal. The AP8700 could overload, but has sufficient gain. The 7777 will overload.
