Hi,
Please, could you help me with this wifi booster I have? I found both 1W and 4W 'versions' on the internet
Would it work as QO100 PA with 110cm offset dish and helix ? (Hungary, Pluto+LNA)
ARGtek wifi booster

Hello Kornel
First the supplier link is recognized by Norton as a dangerous site !!!!!!!
For the PA this remains as "Low Chinese PA quality". I advise you to inform you about the PA of SG-Labs certainly more expensive but of higher quality.
The CN0417 Analog device + 3dB attenuator + SG-Labs combination will give you very good results.

Hi there,
I miss the 1 W amplifier from AD CN0417 and the 20 W amplifier from PE1CMO.

Detlev,
your first link shows products supporting only semi duplex and I do not recommend to promote them here in our list.
Kind regards
Matthias

Hi Matthias,
my 20 W amplifier from PE1CMO is full duplex.

Hi Detlef,
really, are you sure ?
I think everybody should think about whether he wants to buy from someone who is ignoring clear rules of the satellite operator and
even makes money selling such non compliant components.For me I have made my decision.
Regards
Matthias

I will none of this sites promote. Analog Devices is a full commercial company and PE1CMO has no contact address on his site and price list. If you know René Stevens you can order his articles on your own risk.
-
Don't forget, Analog Devices produces also the Pluto.
PE1CMO's price list is in the brochure, but no address! Very strange. I had no problems getting my 20 W amplifier from René.

Here is a very interesting addendum for your "big list".
A very well specified PA with 56dB gain and 20 Watt RF.
This is offered by BG0AUB who also has available an interface for
a Pluto driver.
Pricing is riduculous low. I ordered mine already 2 months ago.

Thanks for providing alternatives. But back to the original question: Would this Argtek work ?
is it only a PA or something more?
"Bi-directional, half-duplex, Auto-Switching via carrier sensing"
-
The product is definitely auto-switching via carrier sensing, which you have to disable for QO-100 operation.
Look in the internet for the similar EP-AB003 booster with all the modifications done to it by many OM's.
You therefore better can go for a real linear PA, preferably with a bit more power.
As you mention the Pluto, the BG0AUB offering including his interface board is maybe the easiest and cheapest.
Good luck!!
-
I operate an EDUP EP-AB003 WiFi booster without any modification with an input of about 400 mW from the uplink converter.
1 Watt output power could work as preamplifier for a big amplifier or at an big dish I think.

Hi,
What preamp do you use to drive this BG0AUB PA? How much gain needed? 4-5W Output should be enough for me with that 110cm dish I guess, so maybe I can run it with reduced input voltage and low drive or?
But, being as a newbie I'm simple unable to understand the spec table you shared the input power column with those negaitve dbm values
-
I also don't understand why all the values are in dBm. To clarify it in my mind I have to convert it into Watt. You can do this also online here: https://www.everythingrf.com/rf-calculators/dbm-to-watts
-
Oh Boys,
did you ever heard, with logarithmic values, gains and attenuations can be added easily instead of multiplying and dividing. We should follow the professionals.
Look forward, please.

OK Andreas, you are right. But to look for suitable pre-amplifiers and amplifiers its easier to calculate with mW and Watt. This is less abstract than with dBm. Or you live in a "dBm world", then its easier for you.
-
Hi Thomas,
I think we use mixed units of measurement: dB for amplification and attenuation and W for the power.
