I’ve reviewed a number of posts about antennas and the good external links cited. But since there is so much knowledge on this forum, I thought I would just post my situation to get some expert advice.
I am in east Africa, in an urban, moderately hilly place. We have multiple providers with multiple towers in range. Our principle provider is giving us 4g LTE on Band 20 at 800 Mhz. But I keep an assortment of sim cards on my desk for contingency. All those others are 3g WCDMA Band 1 (2100 MHz).
I am running a Max BR1 as the edge device /firewall/ cellular router for our network of 50+ W10 clients. We do quite fine, most of the time. But we are a bit vulnerable, since we have shut down all local storage and servers going with Gsuite and Google team drives for everything.
Currently I am using only the BR1’s built in antennas. I have it mounted on an exterior wall because we have heavy reinforced concrete walls, 10” thick, so the reception drops rapidly inside. I would like an omnidirectional exterior antenna that would give solid reception for any of our mentioned providers. Even the better providers have be known to have lengthy (several weeks) outages. And any tower can go at any time, so I need to be ready for anything without touching the antenna – just shove in another sim to get going. My best mounting point is a pipe we once used for point to point up on a second story gable. It would be about 110’ cable run to the wiring closet where I would like to keep the BR1.
I will have to order every piece, every connector, from out of the continent, so I have to get it all right the first time.
Thanks in advance for your suggestions.
