We also use(d) the Webcatcher (from Silentwind).
Easy to install, works like a WLAN-Spot for all your devices.
No problems at all.
What we underestimated:
1. You have often to many masts or other obstacles between you and the source.
2. The costs for internet 4G etc. are - together with an impressive network coverage - mostly much lower than expected.
E.g. for the Caribbean Islands - Digicel. One SIM-contract for nearly all Islands.
Thus it is often much more comfortable and more powerful compared to the antenna/ webcatcher and we use it not as often as we thought.
