    RDF Yagi Antenna for FRS Radio

    I bet your Tonna antennas would be good for direction finding!  I guess you'd need a tank and 40 acres to turn the things though.  :) If I am understanding what you mean, the 1/4 wave bazooka or the 1/4 stub would seem to cost the same (almost nothing) since the pieces needed are virtually...

    RDF Yagi Antenna for FRS Radio

    Thanks again for your response.  In recommending the bazooka, do you feel that it is superior to the cheap Radio Shack type 75 to 300 ohm units?

    RDF Yagi Antenna for FRS Radio

    I am back to realizing the impedances need to be matched. -------------------------------------------------------------------------------- >Scott Fintel said: >Most all of your TV antennas use them to go from 300 ohm leads >on the antenna to 75 ohm cable. And tekwiz at the...

    6v to 12v inverter

    And here I thought you'd make it! http://www.aaroncake.net/circuits/6-12conv.htm

    RDF Yagi Antenna for FRS Radio

    Oops, I care about receiving not transmitting right?  (And the balun reguards matching antenna/transmitter impedances?) "Coupling" the receiver to the antenna is my concern correct?

    RDF Yagi Antenna for FRS Radio

    I looked up baluns in the 1993 ARRL Handbook.  The bazooka balun (Figure 14B, page 16-7) looks like it will balance the impedances if the bazooka sleeve is 1/2 the length of the driven element.  Have I got that right?

    RDF Yagi Antenna for FRS Radio

    Thanks again for your reply.  You are not putting me off at all. I need to learn at least a little of this and thanks to you I learned a couple new terms. Yagi Cad says this design that seems good and that ithas input impedance 11.6 +j 0.0 Ohms I can research how to make a balun but I'm not...

    RDF Yagi Antenna for FRS Radio

    Thank you very much. I'm glad you've used the program successfully.  It sure looks like a novice like me possibly could make it work. I'll use the YagiCad program to design for 465.13 Mhz. I understand that I am looking for a foward looking pattern as shown here...

    RDF Yagi Antenna for FRS Radio

    Hi All I am afraid that I know nothing about RF. May I appeal to you for help with this project? I bought 4 FRS radios and am about to equip a few rockets with them in a manner similar to this: http://www.nakka-rocketry.net/frs.html#top The radios that I have are capable of continuous...
