No, the antenna connector heats up and will definitelly melt the hot glue. I usually add a piece of heatshrink tube on the antenna connector.

I would not bother about the heat issue, unless you hide it into some enclosure where it will not have enough cooling. BTW: The front side heats more than the back side. You can even mount the heatsink if you want.
Many thanks!
