Increase effective distance on 'ebay' flash remote trigger transmitter with antenna

Step 5 Modify the antenna shape?

You could even choose to make the antenna shorter by twisting it a bit into a curlicue.

I used a pen cap and twisted the antenna around that. It looks nice, but seems to have little effect on the design.

For optimum range, you should leave the antenna straight.

Coiling it like this creates an inductor that effectively makes the antenna longer than its physical length. It may only be nanohenrys, but at these frequencies, a little inductance goes a long way.
