Attention Canadian customers!
The prices shown on the site are USD, you can convert to CAD during chekout.


The long range systems you on this page may require a HAM liscense for legal
operation in your country, please check your local regulation.

Also note that they are not plug-and-play, it require some basic soldering to wire them.
We can help with radio integration or provide turn-key systems, just contact us.

7W booster
New V4.00 version!

NEW FEATURES of V4: added safety and security
Auto power on from 50mW input it will power up
if no RF signal input it will idle at zero current, so it can now be left powered on all day long
LED indicator one dual color, red-green
Green lit constantly = all is perfect, RF level in is fine, and DC supply is fine
Green off blinks start at 150mW and down to 50mW, longer and longer off time = less input power
Red blinks show input voltage is under 6.8V
longer and longer RED lit time when voltage drops more.
Green and Red blinks can be active at the same time in case both low rf level and low voltage
booster still works at different voltages, and can now be powered as low as 2-3V

The booster will give good power from 125mW to 500mW input
500mW is nominal input, 125mW is -6dB accepted max cable loss, at this point output will drop 1db
input will survive 1W for 10 sec, and 2W for 2 sec, maybe more but I did not dare to test the kill time

The previous booster versions had idle currents in the 400-600mA range, so booster could not be left powered on when not flying
risk of using all battery power existed. Users with V3.x boosters must be aware of this.
Idle current is defined as the current the booster draw with no RF input

Idle current for booster V4 is only 1.4 mA !

This PA booster is designed to get 500mW input from the V3 RC system
Boosting 0.5W to 7W will increase the range by at least a factor 3 !
The PA module consume about 2A at 7.2V and give 7 to 8 Watt out of pure long distance RF power.
