[Yet another Antenna question]

I have some Baefeng 888s.  I haven't played with them much but I have got them programmed I am thinking about replacing the antennas cause I hear they're just but I'm clueless. Has anyone tried these anttennas or know anything about them?  One  and Two

 

Thanks!

[Now What?]

I got myself a BAOFENG UV-82 cause I plan on eventually getting my tech ham lic.  But for the rest of the family I got 888s that I've used CHIRP to program with tsql to help filter things.  I had thought about the radios but I'm told that Carnival hasn't any issues with them.

[Now What?]

Hi all, I just paid my money and got my GMRS lic yesterday.  So now I've got my lic. I've got my radio.  So the question I've got is now what?  The reason I went ahead and did all this is my brother's family and mine are going on a cruise in a couple of months.  I though the radios would be good for the trip.  But I've got a new toy and wanna play .  Any suggestions?
