Hi Al,
well yes and no!
sure with yagis (for those not knowing what a yagi is ...its a directional antenna design like your tv antenna)... you can do some astronomy ... such as drift scans of strong radio sources etc ... you can also look for solar noise bursts etc ... but probably more interesting is meteor reception or radio based aurora reception.
I guess rather than worry about what antenna you have its more important to worry about what receiver capability you have .. ie what frequency coverage and type of receiver. Ie a wide band HF receiver, or a AM/FM only scanner for VHF or a modern multimode wide band receiver that is capable of HF through to high UHF ranges.
So I guess to kick off the discussion thats more important.
Antennas can be built from all sorts .. and in particular NZ / AU have a lovely thing called C band Satellite TV.... which gives a vertitable treasure trove of astronomy parts.
but ... lets look at the basics first!
