It will work with very low quality. You have to search for Marine VHF antenna, at least 3dB preferably 6 dB

thanks for the answer,now i've got another question, i have an ais connected to an antenna on roof, i also have a handheld vhf station which i want to connect it to the antenna.I bought a BNC splitter with one entry and two exits,i connected all three of them and it seems the ais receiver works well, it receives the signal , however the portable vhf it doesn't,any ideas?
Note: the vhf station is only use to receive , not transmission!

It wasn't any brand , it was just a passive splitter .Well that solution didn't work because the signal was reduced very much also for the ais receiver and for the vhf station so i gave up.I got another antena for my vhf station , it's a Midland Shark 4  now i'm having a hard time trying to figure it out how to connect it to my handheld vhf, i tried a few methods however the signals is very very weak, and i don't know where could be the weak link.My hand held vhf is a horizon hx260e , i removed it's antenna , i put a screw which fit there , i connected the coaxial cable and isolated it, however signal is very weak in comparation with it's own small antena put outside.Any ideas?
