    Try building a quadrifilar helix antenna. Best yet I have found for NOAA. N7LRY has the best plans for one. Where your at I would think you would be pleased with the performance.

    Good video for ppl who want to try this out.
    I did it a few times and it is fun; now though I click on the NOAA website for HD images. ;)

    I have found that a discone antenna is nearly ideal for receiving orbital satellites. It's also very useful for many other operations because of it's very wide bandwidth.

    Thanks for that. Very clear and instructive.

    KB7TBT- Thanks agn for the video.. If you let the recording continue, or at least continue to receive near LOS (loss of sig) @ the horizon, you'll often find that you can receive these NOAA sats as well as the ISS ,a few degrees below your local horizon. The decoded apt image will suffer greatly due to poor snr.. but you can still dig out the audio in the noise. There are a few sat antennas that are easy and inexpensive to build if you require better snr and 'no null' decoding.. Or, just for general Oscar sat use. For example the "T-R" (Turnstile-Reflector) antenna.. I built this one from the old 1st ed. ARRL "Sat Experimenters Handbook".. This antenna is two crossed 145 MHz dipoles, fed out of phase with an 8inch piece of 75 ohm coax cable. The dipoles are spaced about 3 inches apart.. These are placed about 19 inches above a wooden 'picture frame'.. In the frame is a 19 in square piece of 'chicken wire' from the hardware store. The chicken wire acts as a reflector and adds additional gain.. The dipoles are fed with a single piece of rg8 mini etc... cheap and very low level nulls, regardless of the polar orbital pass and inclination.. 73, n6spp-cm98
