    I have a Dish network 500 dish antenna and wonder if it can be converted for amateur radio use.

    I have heard it can be used on SHF bands,
    Though I am not shure. Good Luck,

    It's like deja vue all over again.

    Does this mean that COWS is going to post another die pole thread?

    No but it would work well as a reflector for a 800mHz heliacle.

    I was thinking in terms of 1.2 Ghz.

    You have a great memory. That thread was a while ago

    The antenna in question is actually spelled "Dy Pole." For those who recall, the Dy Pole is constructed out of 6" diameter sewer pipe. The gain of this antenna is truly amazing. Numerous people claim to have worked over 300 countries in just a month of casual operating with this "unbelievable" antenna............I'm gonna be rich, I'm gonna be rich!!!!

    I thought it was on or under the ground?

    Getting slightly back on-topic:

    What is the diameter of your dish? (I believe there are a couple of different sizes.)

    The ARRL Antenna book has some info; in general, a dish is only practical for the average ham at 432 MHz and above. Bot at 432 MHz, a 2' (24&quot dish will only have about 4dBd gain, and at 1215 MHz, a 24" dish will have about 13 dBd gain.
    Similar gain figures can be achieved with other antenna designs when compared to a small dish, and are often easier to build and feed. A 24" dish certainly shines (no pun intended) at 10 GHz, where it should have 31 dBd gain!

    For further information on using the small dishes such as yours, you can search QST several years back, (esp. articles by N1BWT) The ARRL UHF/Microwave Projects Manual, Vol. 2 has a section on the small dishes, including a way to determine the focal point and suggestions on feeds for such antennas.

    But by all means, go ahead and experiment with the antenna. (And if you have the complete antenna system, you already know the focal point without having to determine it by measurement or calculation&#33 Just remember that the DSS dishes (at least most) are "offset" feed, so the focal point isn't directly above the center of the antenna. Have fun!
