My dos centavos...sent direct to K7XQ yesterday evening. Sounds like the other
responses, but I think more radials should do the trick even if they are not
straight or uniformly spaced, although elevated ones should be as straight as
possible. 73, JH W6UQZ

Some advice, from a ham who worked 93 countries on top band from an apartment
in Monterey, including 9 EUs in one nite, several African countries, and deep
into Central Asia, using a full-sized zig-zagged and bent inverted L. YOU NEED
MORE RADIALS....7-9 minimum if your feedpoint is on the ground, only 4 if it is
raised 10' off the ground. Do you have a metal fence around your property? If
so, connect that up to add to your radial system. You can also use a Folded
Counterpoise system (look up W0UCE and K2AV). A listening loop (made of
hardline) or rotatable Waller flag RX antenna would also help immensely. I
used my TX ant as the RX ant. So....adding radials (up to 60 if you can manage
it) and an RX ant is what you need. 73, JH W6UQZ

Hello All,
I just assigned myself onto this forum, its been a long time and needs some
help and would appreciate some questions answered on this huge experienced
based forum.
First, I want to describe my problem. I have a 1/2 acre lot in the back
property where I install
my antennas. The largest HF antenna is a HyGain Hy Tower which works great
on 40 and 80. On 160, I
run a separate radiator that runs up the side of the hytower separated by 6
inch insulators up to
the top and then runs horizontal sloped from the top of the hygain hytower
downward to a fence support
that results in a full sized 1/4 WL inverted L on 160. The 160 meter
feedpoint is common to the hytower
feedpoint.
I live in the central valley of California which is only about 300 feet ASL.
I do not live near the coast
nor live in the "high desert ".
Some facts regarding this station:
1. I still have not copied or worked into Europe. I have been on this band
somewhat seriously for at least 5 years
2. I hear a few Russians but they don't hear me.
3. I heard a FM5 last few nights peaking 559, called him countleesly with no
QSO. My power is about 800 W on this band ( single 3-500 ). I am looking
into finding a single GS35 amp for all bands on HF....love that tube.
4. I don't have the capacity to erect a full size radiator on this band
although I am curious about the Titanix 160 vertical, what it is and is it
worth looking into ?
5. I have read a lot about the K9AY RX loop. I have room for is antenna but
before I construct one, what are your opinions ?
6. I also read about a 225 foot beverage run close to the ground as a RX
ant. How does this compare to the K9AY loop ?
7. What is the best "short 160 vertical configuration" that has the best
performance for working DX ?
8. You will notice I mentioned that I only run a single ground radial on
each band. Would adding lets say 3 more
Make the difference between night and day for TX or RX ?
I think that's about it for now...73.....
