Hannes has obtained results with a 23-element Yagi antenna at 429 MHz with the B0329+54 pulsar.

Results With a 23-element Yagi Antenna in 2 MHz Bandwidth

The 23 element Yagi antenna used by OE5JFL to detect B0329+54 in a 4 hour long data run...

Hannes says...

"  I wrote some time ago, I wanted to show the possibility using a single yagi antenna on 70 cm for receiving at least the B0329+54. Therefore I built a very light construction (wooden boom, wooden pole) of a 23 element yagi following the DG7YBN design, simulated gain is 18.6dBi. That means a dish equivalent of 2.6m diameter with 50% efficiency. Tracking is done manually, and I can split the 5.3m long boom into 3 parts, and therefore it is easy to pack all into a car to go to a site with low RFI.  "

A nice result indeed !

This is a very nice demonstration of the possibilities for amateur pulsar detection using a relatively small antenna.
