    Looking for RF Attenuator

    Can someone recommend a reasonably priced RF attenuator to use with my beeline? Something like this but not so pricey.

    He doesn't seem to be selling his old FoxHuntAttenuator any more. It was the same price. But he has the instructions onlilne at http://www.arrowantennas.com/inst/ifha.html so you could build your own.

    Consider this. That's what I use.

    However, there's an investment of about $10 more in putting it in a shielded box and adding connectors. Plus time.

    Next time you're tracking, before buying an attenuator, try using your body as a shield (hold the antenna vertically, flat up against your body and turn) when you get close. This dramatically narrows the field and when you get a dead area, or as close to dead as you can, your back is in the direction of your transmitter.

    You can also attenuate the signal by holding the antenna just an inch or so above the ground, or by knocking the receiver off frequency.

    Attenuators are nice, but with a bit of practice, you can track without using one.

    James, I built one like the one Will posted the link for. The only issue was getting all the little ressistors in such a small space. I can get to within about 50 foot with mine now.
