HEY,
WANT TO USE 160 AND ONLY A SMALL GARDEN
HERES THE ANSWER... A G0AYD TOP BAMD VERTICAL THAT DOES WORK...
MATERIALS YOULL NEED...
2 INCH PLASTIC FORMER(DRAINPIPE). 12 INCHES
ROUND WOOD HOLE MAKER.
54 INCH PIECE OF PIPE CAN BE COPPER ALI. ( BASE SECTION)
80 INCH TOP SECTION ALI OR COPPER PIPE. TOP SECTION
18 SWG WIRE.
2 SMALL NUTS AND BOLTS AND 4 SOLDER TAGS.
SELF TAPPING SCREWS.

DRILL A HOLE AND ATTACH THE NUT AND BOLT AND SOLDER TAG TO ONE END OF THE COIL FORMER SOLDER ONE END OF THE WIRE.

WIND ON 187 TURNS OF 18 SWG WIRE AND WHERE IT ENDS DO THE SAME AS YOU DID ON THE OTHER END OF THE FORMER.
SO YOU SHOULD HAVE 187 TURNS ON A FORMER AND AN INCH SPACE AT EACH END OF THE FORMER WHERE YOU DRILLED THROUGH AND PLACED THE NUTS AND BOLTS AND SOLDER TAGS.

THEN USING YOUR WOODEN DISC CUTTER MAKE 2 DISCS TO FIT INSIDE THE FORMER.

THEN FIT THE TOP AND BOTTOM SECTION OF THE WHIPS TO EACH END OF THE WOODEN DISCS YOULL NEED TO MAKE UP YOUR OWN SIZES FOR WHAT TUBING YOU HAVE AVAILABLE.
I USED 13 MM COPPER PIPE FOR THE BASE AND SOME ALI PIPE FOR THE TOP THIS WAS ABOUT 1/4 INCH DAIMETER.

THEN FIT THESE INSIDE THE COIL FORMER AND ATTACH 4 SCREWS THROUGH THE PLASTIC INTO THE WOODEN DISCS INSIDE THE FORMER.
THEN DRILL INTI THE BASE SECTION AND ATTACH A SELF TAPPER AND SOLDER TAG AND SMALL PIECE OF WIRE SOLDER BOTH ENDS ONE TO THE COIL AND ONE TO THE BASE WHIP DO THE SAME FOR THE TOP SECTION.

THEN MOUNT IT ONTO A PIECE OF 2X2 ID KNOCKED MINE IN 2 FOOT AND LEFT 2 FOOT STICKING OUT OF THE GROUND.

ATTACH THE BASE SECTION TO THE 2X2 (I USED 3 JUBILEE CLIPS).

ITS NOW A SUBSTAMTIAL ANTENNA SO BE CAREFULL NOT TO DROP IT AFTER ALL YOUR HARD WORK..

DRILL A HOLE THROUGH THE BASE SECTION 12 INCHES FRO THE GROUND AND ATTACH A SREW AND SOLDER TAG SOLDER THE CENTRE OF YOUR COAX TO THIS AND THE BRAID TO YOUR EARTH....

ONCE YOUVE DONE THIS GO FOR A CUPPA AND GET READY FOR THE NEXT BIT..


IF YOU BELONG TO A CLUB THAT HAS AN ANTENNA *filtered*YSER BORROW IT AND THEN GET YOUR VERTICAL ON THE FREQ REQUIRED.IF NOT YOULL NEED PATIENCE AND A SMALL AMOUT OF RF ON THE CHOSEN FREQ.

I FOUND THE ANTENNA WORKED WELL UP TO 150 MILES DURING THE DAY AND WAS GOOD FOR DX AT NIGHT..

IT HAS 8 KHZ BANDWIDTH.......

GOOD LUCK AND LET ME KNOW HOW YOU GOT ON... DAVE G0AYD...
