[EIDXA] 80 and 160 Antennas by W3LPL

[Jim Spencer]

Nelson,

Thanks for the response with your real life experiences.  With a little 
thinking I should have known what was totally unacceptable to W3LPL might 
actually work well enough for the Little Pistols to make a few contacts.  If 
I had my life to live over I would have had acres and acres in the low noise 
country.  Of course I would have done a lot of other things differently.  I 
have fewer than 20 countries on 160 and none of them are very far away. 
Each contact is a miracle!

Perhaps Dewey shouldn't sell his mag loop although he also has a receiving 
4-square to put up and it sounds like that is a lot better antenna.

Thank you.

73,  Jim  WØSR

Jim et. al.

Antenna performance is relative. For me, it's relative to what will fit in
my back yard (60 x 70 ft.) without exceeding an FAA imposed height
restriction of 54 ft. In my 160 meter experience (13 years, 135 entities)
the rotatable Waller flag and the rotatable 5 ft. square mag loop are a
toss-up. Sometimes one works better; sometimes the other works better.
Before dismissing the mag loop entirely, consider whether or not you can fit
anything bigger on your lot. For me, verticals for 160 are impossible (refer
to the comment re FAA restriction). So are high wire antennas. My 160
transmitting antenna is an inverted L (actually an inverted dog leg) that
runs up the 48 ft. tower to 42 ft., then North to a pole on the back fence
at 28 ft., then East to another 28 ft. pole on the back fence at the corner
of the lot. Did I mention that I live in Iowa City about a mile from
University Hospital and all the power line noise and other interference
typical of urban life?

If your goal is to work DXCC on 160, that's enough transmitting and receive
antennas to accomplish your goal, but you can forget about being a serious
contender on 160 meters for the Challenge. Meanwhile, don't sell your mag
loop. Any 160 meter DX'er of limited means (and some well endowed DX'er as
well) will tell you that you can never have too many receive antennas for
160 meters.

Nelson, KU0A

A truly great presentation on 80 and 160 meter antennas can be found at:
https://www.youtube.com/watch?v=ux5UoiYyKNM.  It is a presentation Frank
made to the Frankford Radio Club in January and he really covers the field.
The presentation covers ALL low-band receiving and transmitting antennas,
not just those at super-station W3LPL.

Two things are interesting to note:
    -Small mag loop antennas are not good receiving antennas for DX
    -The Flex 6700 is not a contest radio

Of course, it is about much more than these items.

Thanks again to Dewey, W0YWW, for pointing this out to me.  By the way,
Dewey has a brand new never-out-of-the-box small mag loop receiving antenna
for sale!
