[K3PZN-List] Wire Antenna

[ARC]

Thanks Jeff,

 

I've been ramping up trying to keep busy until I get enough to spend on a HF
rig but until then I'm doing everything else to get ready for it. I have a
28' mast that I'll be using to put up a dipole. I can put up a 40 meter
dipole between the mast and the trees on the other side of my lot about that
high. The dipole would be radiating (if I'm correct) in an east to west
direction since the wire points north to south. I also need to get another
guy ring so I can tie the mast down @ the top as well as in the middle too
and hopefully get a pulley for the top of the mast to make raising and
lowering the antenna easier.  I have a top hat for it but, it's plastic and
I'm not sure how durable it is. I also plan on eventually putting my 5
element 2 meter beam up there as well with a light duty rotator. The mast
should be able to handle that with the proper guying. I've been told the
aluminum masts can withstand 90mph sustained winds but that will go down
with the rotator and beam on it I'm sure. I ultimately want to take the mast
up to 45-50' by anchoring it to the house and guying. Then I should be able
to get the other side of the dipole up over top of the tallest beach tree in
the back yard which is at least 40' tall. That will get it over the houses
and obstructions won't interfere so much. I just have to make sure the
antenna is tuned so I'm not on the edge of the roof trimming wires. 

 

I've been looking all over the net for one but, everything on eham or qrz is
either above my budget, sold or doesn't look worth buying and all the rigs
worth buying on eBay have 15 people bidding on them already, I'm really not
interested in buying from eBay anyway, too many crooks and I really don't
want to get burned by someone I most likely won't be able to contact again!
S'ok though, I (in all reality) have time on my hands and I'm just trying
not to rush into a bad deal...

From, Jeff Edmondson / W3JSE,  Curt Gave You Good Advice ,But  I Will Throw
My 2 Cents In Also. Suggest Starting With a 40 Meter  Inverted Vee.You Can
Operate  40 / 20 / 15 Meters And Occasionally 28 Mhz . The Old Rule Of Thumb
Is 468 Divided By Freq In Mhz. Thus A 40 Meter Inverted Vee Will Be Close
With Each Leg Of The  Vee Wire Being 32.5 Feet For An Actual Total Of 65
Feet. Assuming The Dipole Is Center Fed With A  Feedline Coax To A 1:1 Balun
At A 45 Degree Angle . Leave Your Wire A Little Longer And Adjust As
Necessary. A Manufactured Balun For 1:1 Should Be Around  $26.00 Give Or
Take With A Male  Connection To Couple With Your PL 259 Connector On Your
Coax Feedline   Or Perhaps Make Your Own Balun By Using 18-21 Feet Of Coax
Wrapped Around A Cylindrical Form To Choke The Rf. This Would Give You A
Nice 1/2 Wave Antenna. We Will Keep A Eye Out For You On A Good Used Hf Rig.
