Parts list in the WIKI here: https://github.com/davidkirwan/software_defined_radio_telescope/wiki/Dual-Dipole-Antenna-Parts-List

davidkirwan commented 9 years ago

I've purchased 100M of copper wire which I hope to use for the antenna, and 100M coax RG59 which is not perfectly suited, but may work.

I've also purchased the Dipole centers, and the PL259/SO239 adapters and the PL259 - SMA adapters. Should be arriving in a few days

davidkirwan commented 9 years ago

I now have the antenna wire, coax, dipole centers, t junction adapters and the cable connectors. The only thing I'm missing now is a pole to mount the antenna and insulators. I've been looking at building something with wood perhaps.

davidkirwan commented 9 years ago

I've purchased 12ft plastic pipes which may prove suitably sturdy enough to act as the antenna mounts. Issues with my car has become a blocker with working on this aspect of the build, hoping to resolve asap.

davidkirwan commented 9 years ago

Pipes drilled and supports installed to allow the antenna to be deployed in 10ft and 15ft configurations. Remaining work requires:

davidkirwan commented 9 years ago

Single dipole is deployed. The following parts are required to deploy the 2nd.:

2 ground screws to hold the mounting pole 2 mounting poles to match the first

In order to take full benefit of the dual dipole configuration, ability to steer the antenna is required, parts required to make this happen:

SO239 and PL259 connectors to create the phasing cables

davidkirwan commented 9 years ago

Connectors arrived, can now complete the build on the phasing cable, and a much longer connection cable in order to move the antenna further away from the house and any potential interferance.
