Direct Connected amplifier for EU

[wavemag]

Hi!

Can somebody recommend Direct Connected amplifier for EU band’s
LTE (Band 1) (2100 MHz)
LTE (Band 3) (1800 MHz)
LTE (Band 7) (2600 MHz)
LTE (Band 8) (900 MHz)
LTE (Band 20)(800 MHz)
WCDMA / HSDPA / HSUPA / HSPA+ (800 MHz)
WCDMA / HSDPA / HSUPA / HSPA+ (850 MHz)
WCDMA / HSDPA / HSUPA / HSPA+ (900 MHz)
WCDMA / HSDPA / HSUPA / HSPA+ (1900 MHz)
WCDMA / HSDPA / HSUPA / HSPA+ (2100 MHz)
?
Any contacts of Russia or Croatia resellers?

Hello wavemag,

I’d like to involve @kevin here.
I think he can help you with this.

Hello @wavemag,
Rater than rewrite these previous post from @kevin and myself, here are two quotes on your question.

@mldowling

Our professional advise is DO NOT use any inline boosters connected to your LTE modem (this is regardless of who makes the modems or boosters) focus on using a better antenna solution. Even with one booster per antenna connection, they will still cause more problems than they solve, not to mention most of them put way to much RF power back into the LTE modem and are likely to damage the chip set within the LTE modem (this sort of damage is not covered by any form of warranty).

@kevin

You shouldn’t hook a repeating amplifier directly to a cellular modem. The gain coming off of these amplifiers is well over what an embedded modem can tolerate and you are likely to burn the modem out in a worst case

Have a read through the two full posts for more information.
Happy to Help,
Marcus

Hi!

I agree that weBoost Connect 4g is not an a solution.
Most of booster design to have antennas on both sides. So
if you connect device directly to booster you broke them.
Exist amplifiers that are design to be connected to IOT/M2M device directly. For example
Iot & M2M Devices Cellular Repeaters | WilsonPro.
It is design to connect directly IOT/M2M. But it is design for US market. US marked use 3G/4G bands diffs from EU has.

I can’t install IOT/M2M device near antennas.
Currently device are 12meters far from Antennas. So I loose a lot off antennas gain.
For better maintenance tasks I must move device to another location, so I receive additional 12meters of cable.
So my us case is Antenna <12mCable> amplifier <12mCable><1:2 splitter>PepLink
if amplifier have gain +15dBi I never oversubscribe input of Peplink.

In case Antenna <12mCable><1:2 splitter>PepLink maximum signal I see was -40dBm…
with +15dB I will have -25dBm, I don’t think that I broke device in even in this case.
