Israel, like my own country, has laws in place which forbid the sale of any RF-capable devices until they have been expensively and painstakingly approved by some central regulatory authority. This sort of thing is common in state-heavy countries. The Israelis are just more competent about enforcing their laws and regulations.
In general regulating broadcast RF is a good thing, because it only takes one badly behaving device to spoil the air space for everyone.
You might think that it would be possible to rely on foreign certifications but standards are not totally harmonized between regions and governments worry that local inspection and certification is required to avoid having B-grade out of spec product sold in their market.
