spiro or helical antenna

Hi everyone I have this fpv setup skyzone 500mw http://www.hobbyking.com/hobbyking/s..._Antennas.html

it comes with the left hand spiro antennas, will a helical antenna be better if so which one?

Any suggestions on what other ones I could use if I want to increase the range

thankyou

Those antennas are terrible. A helical will do wonders for your video: http://www.readymaderc.com/store/ind...oducts_id=3734

That should be ok, but I would make your own antenna before using a coil loaded antenna.

What would the advantages be to making my own? Ive used a similiar antenna for 4g internet through a 4 story cinderblock building it was great considering it was 1 or none bars with out it.

I would have to cut and solder an array if i wanted the same gain correct?

^Correct. More gain requires a phased array.

You can make your own DIY antenna much better than the chepies. Trust me on this one.

Check my blog. There are many tutorials on antennas including the helical and the Cloverleaf. You can build a 5.8GHz helical on a 5/8" wooden dowel with 1/2" coil spacing. Nothing to it, really.
