Here is the NEW PA Booster PRO, again like on the TX, running temperature, materials, and improved
design has been the main goal of the new improved version. The black anodizing protects the aluminum for
oxidization, higher strength and better cooling.

FEATURES of V6: 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 V5 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

The PA booster is 77mm wide, 107 mm long, 39 mm

RF cable
The BNC - BNC cable you need to use from standard 500mW tx unit to your booster (is not supplied)
use any 50 ohm impedance cable with loss from 0dB to 6dB at 500MHz.

Network cables with BNC 10base-2 are 50 ohm, cheap and available world wide.

Different cable types have different loss, here is the max length allowed using different cables:

  • RG-58CU 18meters (59ft)
  • RG-223 17meters (55ft)
  • RG213U 37meters (121ft)
  • Ecoflex10 67meters (219ft)

Note: In US the maximum power allowed when transmitting telecommand signals to radio controlled models is 1 watt.
