Can an antenna be too powerful for certain receivers?

I'm brand new to shortwave radio and have been researching what kind of a receiver to get. I'll use it on the antenna I'll build (longwire, 50-100 feet) for shortwave listening; no transmitting. Right now I have my sights on a Tecsun PL-360 as it's affordable and has an external antenna port. My question is: Would the portable ~$40 Tecsun get damaged somehow by a 100-foot antenna because it's designed to work with shorter, portable antennas? I really don't know if that's something I need to worry about when only receiving.

The reason I want such a cheap receiver and not something better but more expensive is because I just want to make sure the antenna's working properly. Once I'm happy with it I'll hook it up to an RTL-SDR device and plug that into a computer. I just don't want to spend hundreds on a receiver I'll only use a few times.
