There seems to be a similar product at Drotek --> http://www.drotek.fr/shop/en/home/642-radio-telemetry-kit-433mhz-50...

I recommend anyone looking for better range to get antenna's suited for 915 over the stock whips, first!

Great news! If only they'd integrated the minimosd as well, as they did with their other product.

I am particularly glad on the 433mhz 500mw and their price.

@Martin Drotek might be first to have it but you cannot beat hobbykings price.

I've never heard of, nor can I find any information on a HM-TRP with 500 mW output power.  In looking at some of these pictures, it looks like the module is connected directly to the antenna, so I don't think there is an additional PA.  Also, the module looks different than the 100 mW HM-TRP.  Does anyone know what module these devices are using?

Into a mismatched antenna 500mw just generates heat. 

Comment by Martin on March 23, 2015 at 10:32am

There probably is a PA and an LNA on-board.

The drotek model appears to be a standard HM-TRP, and it looks like there might be another module on the back, but the model on readytoflyquads looks like a different module, and the module appears to be clearly connected directly to the antenna, which means there is no extra PA/LNA.

If you compare the module layout to a standard HM-TRP module you'll find that there are at least 2 extra chips. I wonder what those are.
