| THIS IS A EASY HOME BREW PROJECT THAT IS LOTS OF FUN TO BUILT AND WHEN TESTED AGAINST A CUSHCRAFT 3 ELEMENT THE HOME BREW SURPASSED IN PERFORMANCE IN BOTH TRANSMIT AND RECEIVE. TESTING WAS DONE BETWEEN 443.000 AND 448.950 |

| DIRECTOR AND REFLECTOR ARE MADE OF 3/32 DIAMETER COPPER PLATED STEEL WELDING ROD. DRIVEN ELEMENT DIPOLE IS 2 ADJUSTABLE LENGTH SCANNER ANTENNAS. RG174U BELDEN 52 OHM FEED LINE CABLE WITH A RCA CONNECTOR ON THE END. TO CONNECT TO THE HT USE A RCA TO BNC, IF YOUR HT HAS A SMA ON IT USE THE SMA TO BNC ALSO. |
| MY FIRST TEST WAS THE IRLP IN OMAHA, BRANDON HEARD MY CALL AND WHEN HE CAME BACK TO ME I TURNED THE ANTENNA FOR MAXIMUM RECEIVE AND ON THE SECOND GO ROUND HE REPORTED THAT I WAS FULL QUIETING. I WAS USING 1 WATT. |
| I SET THE UNIT UP ON MY BACK PORCH AND POINTED TO KB0QKH 16 AIR MILES AND MADE A CALL WITH JUST 50 MILLIE WATTS. JOHNS REPORT WAS 100 PERCENT PERFECTLY READABLE WITH JUST A LITTLE NOISE. |
