Thread: Newbee Survivalist question

  1. #1

    Default Newbee Survivalist question

    I'm a 65 year old grandfather who would like to be prepared in the event some parts of the communications grid fails due to natural disaster or other causes. I live near Houston, TX and have kids in Dallas, TX. I want to put something in both of our houses in preparation for a disaster so we can communicate. Money is not a big issue here, just want something that will work. Thanks.

    Maybe C.B. radio is the way to go?

    It's a pretty long way (maybe 250 miles) VHF & UHF amateur gear would be a pretty penny for a reliable repeater link, plus you'd have to be licensed at both ends.
    H.F. is not guaranteed either, like C.B.

    Will C.B. go that far?

    No, CB will rarely ever work that distance. In fact, 11m CB is the least likely to work for 250 miles. That is well outside the ground wave coverage and anything ionospheric will not work as CB cant make short hops (aside from the occasional auroral or sporadic E) because the wavelength is too short to be refracted at high elevation angles and signals are lost to space. This creates a "skip zone" of no signal before the low angle signals hitting the F layer reappear about 1000 miles out. CB is absolutely great for reliable coverage between 30 and 75 miles (depending on terrain), and when solar activity is high, long distance hops are easy (still, not for 250 miles). The only hope of making CB work that distance is to run beams aimed at a common back-scattering point in the ocean and I highly doubt anything reliable will come of it.

    That distance is going to require a ham license to run HF or high powered VHF.

    Edit: You could always acquire a few friends with CBs between the two locations and start a CB relay network, have a Sunday net, make a hobby of it...

    Assuming the disaster would wipe out 2m/70cm repeaters + cell phone towers, you have only one option to communicate with someone over that distance.
    You did say money wasn't an issue. Therefore your answer is to buy a couple of satellite phones.
    Not a cheap conversation, charged by the second or Min. But unless someone shoots down the satellite communication will be possible from/to anywhere on the planet.
    Hope that helps.

    Have a look at "Garmin inreach". The lowest monthly charge is about 14.99 ($18.50 USD).
    Then compare the contracts from other providers. May get a better deal for am annual contract. The above mentioned price is for a monthly contract.
    A satellite SIM card is much the same as a cell phone SIM card. Only it costs more.
    So have a look at the various sat phones on the market & the best contracts to suit your needs.

    I done a little research. Google "iridium prepaid SIM cards".
    You can get one with around 300-500 Min which is valid for 365 days (12 month) for around $500+ USD.
    Then you need to buy/or rent an iridium handset.
    There are several different providers. So you need to find the best deal.
    I reckon it would cost you in the region of 2 grand + to buy 2 handsets & 12 month SIM cards for them.
    But that price would be reduced after a year if you had bought rather than rented the handsets.

    So you need to ask yourself. How much it would be worth to talk to your family in the event of such a disaster?. If it was myself, l would say no price would be too much if l could afford it.
    Fortunately my family lives close enough to me.

    There are other satillites up there. The iridium ones are in a low orbit. You may get a better deal from the other networks.
