I mainly don't want to bother changing them one by one, so I plan to get a set that covers everything at once. Otherwise, constantly upgrading would be too expensive. I also want a good antenna with the following requirements: "It shouldn't be too large, easy to carry, preferably packaged and ready to go, with a coverage range of at least 500 km. If it could cover 1000 km, that would be even better. It should have good interference resistance and strong penetration." After thinking about it, this is something the US military hasn't been able to achieve...
