Richard, what you want to do is probably a good idea.  The RX antenna is for 
all bands below 6 meters, so your 10 meter loop is in that range.  What you 
want to do is improve the signal/noise ratio, and your loop will likely do 
that.  For example, a Beverage antenna, named for its developer, Dick 
Beverage, is really not a gain antenna at all, but has a good signal/noise 
ratio, so it's mostly used on low frequencies such 160 or 80 meters, where 
the noise level tends to be high.

The receive antenna is used only on receive.  When enabled, you receive with 
the receive antenna and transmit on the main antenna.

Hi!



Page 76 of the TS-2000 manual says: "HF RX ANTENNA - If you have a separate
HF antenna (below 30 MHz) only for receiving, connect the antenna coaxial
cable to the HF RX ANT connector on the rear panel. This connector is
considered to be connected to a beverage antenna or directional loop antenna
for low- band operation."



I intend to make a 10M full wave loop antenna to connect to the RX only
antenna jack of the TS-2000.  Right now, I use a multi-band 43' vertical
antenna (6M - 160M) for 10M operations (phone).  Although this vertical is
pretty good at TX, it is pretty noisy at RX.  Often, I encounter a weak
signal that is hard to pull-in.  So,  here is where I am thinking of
employing the 10M RX only full wave loop antenna.  Therefore, I have the
following questions about this:



1)       What does the language in the manual (above) mean when it says "If
you have a separate HF antenna (below 30 MHz) only for receiving"?  I intend
to make my antenna at 28.4 MHZ.  Because I am only a Technician Class, my
10M phone privileges are only in the range 28.3 MHZ - 28.5 MHZ; hence making
this full wave loop at 28.4 MHZ.  Essentially, will my antenna work?

2)      What does the language in the manual (above) mean when it says "This
connector is considered to be connected to a beverage antenna or directional
loop antenna"?  What is a "beverage" antenna? What is the difference between
my intended "full wave loop" versus a "directional loop" antenna?

3)      Am I correct that when I am operating and tell the TS-2000 to use
the RX only antenna TX would still go out to my 43' vertical, and that no RX
would be heard from that 43' vertical?



After I upgrade to General Class, I think I might put a 40M or 80M full wave
loop antenna onto my TS-2000.  Presently, I have the 43' vertical on the
TS-2000's "Ant 1" jack and a 6M J-pole on "Ant 2."  Whether I put this
future 40M or 80M full wave loop onto the RX only, Ant 1 or Ant 2 jacks is a
question for another day.



73,

Richard KK6MRH
