TURN YOUR GUTTER INTO A SHORTWAVE ANTENNA

Hello and welcome back... This is a great idea..

I thought this was a joke when i first heard of it, turning your rain gutter around your home into a shortwave antenna...

But its not and... It works

I decided to give it a go, and was surprised just how much of a signal i got.

This idea would be perfect for people in rentals, unit blocks or just want a stealth antenna without the normal antenna's gaining unwanted attention.

All you need is a downpipe close by (the shorter the wire run, the better) and screw in a wire attachment / lug (see photos below), then connect to your shortwave antenna and watch your radio come alive... give it a go.

THE IDEA (from facebook post)



MY SETUP (using a metal elbow pushed into a wall bracket)


SIGNAL BEFORE (a very weak signal - even with the retractable antenna fully extended)


SIGNAL AFTER (attached to the gutter - signal excellent)

OVERALL AN EXCELLENT RESULT...

BUILD YOUR OWN FLOWER POT ANTENNA

Hello and welcome back... I'm going to try this, looks really good.

Build your own 6db gain Flower Pot Antenna from coax that you probably have laying around your house.

Its called a Flower Pot Antenna because, the original antenna was cleverly disguised in a flower pot.

The clever inventor of this antenna is a NSW amateur radio operator  (VK2ZOI) and the instructions to build this antenna are on his website. (see links below)


View the instructions on how to build this antenna here

HOMEBREW BUDDIPOLE ANTENNA WITH MODIFICATIONS

Hello and welcome back.... Found this video interesting and gave me a few ideas.
If your into Amateur Radio or Scanning on the move, this is a great setup. The pole system is similar to my setup... I have a pole that extends to 3 different lenths and is mounted into a Foxtel pole supporting a satellite dish, it gives great stability in wind but this idea of the 3 zip ties to tie into the ground is an excellent idea.... I'm impressed, the rest looks simple to make... see what you think.

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.
