MAKE YOUR OWN ANTENNA

Hello and welcome back..... This looked interesting, Its from a Magazine called 'Siliconchip'.
Build your own Collinear Antenna mainly for Aircraft but you can change the lengths to change Frequencies.... Best of all, Its from parts you probably have already around the house, mostly Coax and PVC Piping.... Check it out.

Thanks to  SILICONCHIP.COM.AU for the info
