In a total steel
yacht nothing works free w/o external antenna
. The Locomarine 4G Yachtrouter is a very civil piece of work but a bit of overkill on a 33 ft loa
boat. Plus, as Karl said, quite expensive. I have an Irridium phone
for use at sea and abroad, avoiding extraexpensive costs of roaming. Next to that I have my special phone-setup for inland use. Both work with external antenna's, fixed up en next to the mizzen and transom. The WiFi
or MiFi is inside the boat with an extra antenna
mounted on a pole at the transom.
Because of the umbrella effect a MiFi antenna should mounted not too high up.
I can have up to 10 users on the Huawei hotspot. Friends, who bring their tablet(s) will have access to internet
as long as there is a mobile phone
connection is available.
For fibreglass boats everything changes and more simpler gadgets may be used.
