Making a little antenna switcher... toggle/rocker/knife?
I'm putting together, as a quickie project, an antenna switcher. I
didn't have good results with an old rotary switch I had on hand so I'd like to make it simple: one switch per antenna, and just have clicked on the one I want and clicked off the one(s) I don't. Are there certain types of switches that work well for this app? Others to shy away from? Since RS is close I'd like to visit the Shack and be done shopping if I can. Thanks. |

- My advice would be to look at the external antenna plug.
Then stroll down to Radio Shack, and look for switchable dual in - one out Hi Fi or VCR / DVD components. - The staff may try to sell yo a Cell 'Phone or Sat dish; Aside from that, Some of the gold plated stuff looked interesting.. Alligator clips, Duct tape, shielded wire all should help Dan In article , (TommyBoy) writes: I'm putting together, as a quickie project, an antenna switcher.

Use what ever you have on hand, it really doesn't matter as long as you're not
worrying about handling power from a transmitter. jw wb9uai |

With a little soldering ingenuity, a Ratio Shaq speaker selector should make an
adequate antenna router. An add-on hi-fi aux box could also be modded & utilized. |

An RF A/B switch should work to TV channel 69, should it not?

The shortwave spectrum reaches 30-Mhz. A video switcher might attenuate the higher HF range. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- |
