Depending on the nature of your outage...
Depending on the nature and cause of your outage, a principle similar to CONELRAD (CONtrol of ELectronic RADiation) may be in your best interest.
Do you want people to know you've made preparations to survive the coming crisis that would follow in a grid-collapse Road-Warrior type situation? You'd be talking about a world where, until the crisis was over you'd be on your own. People fleeing cities en masse. Gangs of looters trying to scrounge what meager supplies they could find, just to make one more day, or week, or month. People unconcerned with your plight-people unapologetic about their own lack of preparations and desparate enough to kill you and take yours.
That being said...
The communications that will benefit you the most are going to be the ones that will help you communicate down the block, from house to house, among the neighbors you've known for years if not your whole life. Five, maybe ten miles. In fact, from a security standpoint, unless your positon is unassailable, unless you have enough defensive capability to repel assault by a determined or desparate crowd, you may want to limit your comms to within 1-2 miles.
Trisquare makes 900MHz spread-spectrum radios that would be practical for this-they're a bear to track using the RDF equipment I'm familiar with...
I would concentrate more, at the point of a global breakdown, on hardening my own home, making it look less desirable to any scavengers, making it look harder to access and less worth their while to come in.
As for the longer range comms, if it became necessary, I'd send a rider (bike or horse, whichever made the most practical sense) about five miles down the road with the absolute minimum equipment necessary to establish communications-a small SLA battery, fully charged. An HF radio and two or three simple dipoles to communicate on 80, 40, and 20 meters Maybe an MRE or some smoked meat if he was to be gone for more than a couple hours, and a rifle. The long range comm scouts would carry equipment that has a minimum ammount of value for the simple reason that if they're overrun or lost, the material loss would be minimized.
Alternately, I would leave the long-range comms to the people SENDING me the information, and glean what useful knowlege I could from them.
