https://www.ladyada.net/make/wavebubble/ https://www.ladyada.net/make/wavebubble/ >> This website details the design and construction Wave Bubble: a self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camouflaging: it is the size of a pack of cigarettes. >> An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). The battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). >> Output power is .1W (high bands) and .3W (low bands). Effective range is approximately 20' radius with well-tuned antennas. Obviously jamming GPS is not really a solution to this problem. However, as hostile use of GPS grows, building something like a Wave Bubble seems increasingly useful.

Be very careful, jamming certain things is absolutely illegal in some countries.

Operating radio jammers is likely to get you a $20,000 fine the first time they catch you, and if they get a hint of your activity, the FCC will absolutely start hunting for you.

  In what maner are they "hunting" some person who is use only on ocasion in locations not fixed? I think these rule are wrong. Some person who is putting up jammer with a range extent only for his propertey should not be in criming.

    They have vans with lots of radio equipment which they will drive around to find you. You’re not allowed to interfere with radio resources which the public owns, even for someone else on your property. Some hotels have gotten fined for interfering with wifi hotspots for example. You’ll be hard pressed to build a jammer which is loud enough to interfere with signals just on your property and not interfere outside or be detectable. You also don’t own the sky above your land and can’t take away radio spectrum from aircraft, etc.
