I saw this video on YouTube that shows a slide show of how to build a vertical Dipole for little less than $20 US. It can also be found at http://www.aurfscan.com.au/showthread.php?805-Antenna-project-Dipole-Antenna in the forums area. The author of the project is "Darren".

How well will aluminum work as a receive only antenna compared to that of Copper used in making the J-Poles?

I am going to build one cut for the VHF Aviation band (AM). The measurements used in the project are in metric, so I converted them to U.S.
I am trying to find the Center freq. in the Aviation Band.
Is it 127.75? because, in my area of Amelia, Virginia, this frequency has activity on it. Since I am not going to Transmit on it, I am going to cut the material for this frequency.

I can also opt to use PVC and encase the elements inside to weather-proof it.
I am also using a "T" conduit that has a removable cover to allow access to disconnect the terminals for transporting. It's going to be as a portable/base.

Has anyone here ever built something like this?

Sean

It'll work just fine. The only reason copper is used for J-Poles is because it can be soldered easily. Many (most?) commercial antennas are made from aluminum.
