We've been shipping the JM132841-EU for a while now, and it covers CDMA/GSM from 851-960MHz, DCS/PCS at 1805-1990MHz, 3G in the 2110-2170MHz range, WiFi form 2400-2500MHz, 4G LTE at 790-820MHz, 4G Wimax from 2620-2690MHz, GPS L1 between 1500-1600MHz, and LoJack from 165-175MHz—so basically everything a profesional setup might need, and the 16W total output gives you about 50 meters of effective range depending on local signal strength.
Most buyers are from conference centers or schools, but we've also had churches and gas stations order a few, though for those places you'll typically want to keep power lower to avoid affecting nearby buildings, and the independent adjustment per band makes that pretty straightforward. 3. It's not great for outdoor events where you need to cover a defined perimeter—the omnidirectional antennas are fine for a room but bleed a bit, so you're better off with a directional setup for that sort of thing. 4. Actually, one detail that surprises people is teh weight: 6.0kg feels heavier than it looks in photos, so factor that into mounting plans, and it runs on AC 110-250V or DC 24V 5A with the power supply included. 5. Bulk pricing usually kicks in around 10 units or so, and lead time is roughly 15-20 working days after order confirmation, though we keep some stock for quick dispatch if you're not picky about custom frequency bands. 6. Lead times can stretch to 4 weeks if you want a specific band configuration or output power tweak, and we always send a COA with each unit, but double-check shippng regulations first since customs varies a lot on these.
Up to 50 meters in open areas, but expect around 20-30 meters indoors due to walls and interference. The range depends on local signal strength and building materials.
Yes, each frequency band has its own independent power adjustment, so you can dial up or down GPS L1 and LoJack without touching the others.
We can provide a factory test report and CE marking upon request. For specific certifications like FCC or RoHS, please confirm with us before ordering.
MOQ is 1 unit for sample orders. Bulk orders usually ship within 7-15 days after payment, depending on stock.
Keep it in a cool, dry place away from direct sunlight and moisture. The box it ships in is fine for storage. Avoid stacking heavy items on top.
