Easiest way of boosting mobile phone signal?

 Not as neat as the Avtex solution - but I use a TP Link router and a Poynting aerial attached to a 10' aluminium mast which is secured to the jockey wheel post with the usual aerial bracket. The lead comes in through one of the front windows set to 'fresh air'. However - it does avoid having to drill any holes in the van and only takes about 5 minutes to set up once on site and it is, of course, quite a bit cheaper.

It gives far better reception than a mobile phone and I typically get 35-55 Mbps download in most areas - sometimes up to 85 Megs.  I use an EE sim, but the router is unlocked and will accept any sim card.

Getting the antenna as high as possible is the key to a signal.  A caravan is in effect a Faraday Cage and even puting one's mobile on top of the roof outside a rooflight can make a huge difference.  Where signal is a real problem I use a router in a watertight box at the top of my longest mast - about 20' up.  No leads needed as downlink to devices is wifi, and a small solar panel shares the box with the router. 

Coverage maps should suggest the best SIM to be using, but always worth trying others. Beware local blind spots, also try moving mast about a bit.

RichardandRos - Snap! just installed the same kit. Have a temporary lash up using the 4 suction feet provided with the aerial. Although it works OK, I think the addition of a pole (like yours) may improve matters further.

Found a photo

I found this the other day from the Trudgians , it's a portable external wifi router for caravans/MH that requires no drilling for an external antenna which can be as high as you can get it.

RichardandRos, thanks for the photograph, I will find something similar. I very much liked your post regarding the E&P hydraulics unit. The Alko wheel locks are a nightmare on my TA van because the storage yard is uneven and twin motor movers mean that I have to crawl on the floor to locate the trolley jack. It slipped and skewed the caravan around recently and I am now committed to getting this fitted. I doubt that I have the same payload allowance as you (mine is 232Kg), but I will look for weight savings elsewhere so that I remain within the MTPLM. My Touareg is still going strong and I am not sure I would want to replace it with anything else. Best regards Dave. 

Hi 

I got a mobile phone booster  with  a outdoor antenna and one for indoors  guaranteed  to up your signal from one bar to five bar  the best thing which works  the best  and  no.sim card in the booster at all just the SIM card in your phone  and no running costs just the electric to run it.

I had my for years and  works really well.
