Thanks for that C2, so should I just be using a standard C - R circuit...

The Yagi Arial that I have obtained is made specifically for 173Mhz frequency, Falcon Telemetrics so not sure if building my own would help in any way...

I have tried to upload an image, just not sure if it's clear enough as I got it from the web... but basically it shows how I am attaching the telemetry and the way it hangs down the tail...

At the moment the end-cap only takes 3xLR41(AG3) batteries so 3.6V or I can use the other endcap and use 2xLR754 (AG5) as either is recommended by the manufactorer just not sure what the difference is between the two...

So what can I start off trying?

Would you recommend testing a band pass filter, but does the whole design need to be no more than 50 ohms...
