2.4Ghz 500mW Pen Booster Range test


Just to let you all know, I've just come back from a range test using the 500mW pen booster tx mod discussed here before.

My freind was in his apartment in town. I drove to a golf course on a hill we can see from his balcony (just, due to other large buildings to the left and right.

He powered up the Tx, I hit the rx power and I got a green light instantly. A quick check of the controls, then I powered up the video Tx (1w 1.2ghz).

Still full control no glitching.

I've just calculated the distance using google maps distance calculator...

2.8 miles.

On the ground (well I was, he was 6 floors up).

Also, just to note, this is a range test of a system to be used in Thailand, and definitely not near any other rc pilots!

Cheers,
Dave.

Futaba 6ex 2.4ghz Tx.

Antenna on the Tx is the one supplied with the pen booster.

Rx is a 617fs, with the aerials set at 90 degrees.

Nothing special.

Just to clarify,

This was a control Tx / Rx test.

I powered the video tx, but did not have my ground station powered up.

Video range testing will be performed next.

yup,

I got mine from ebay (uk).

Try this link.

also, it looks and feels like a quality bit of kit, obviously I can't vouch for the internals, but for what it's worth the body (heatsink) is metallic, and was nicely packaged etc..

The question is, do I need an attenuator like this: http://cgi.ebay.com/ws/eBayISAPI.dll...T#ht_500wt_817
to protect my TX

All those URLs are broken because they were copied from from
a displayed web page, rather than copying the links themselves.
