Hi

i have the MR600 router in my motorhome and use it as a mobile unit, it's currently attached to a roof mounted maxview 3/4g omni antenna. This gives me poor to mediocre connectivity so I'm looking to upgrade the antenna in the hope of improving performance. I prefer the low profile of the puck but I'm unsure of what model to go for? Primarily used for streaming/watching avtex smart tv, social media, internet on mobile phone/tablet etc. 

Currrent system worked well in France and Spain but is generally poor here in the UK.
