K3, KPA500 and KRC2 Antenna Connection Questions

[Jack]

I am considering buying a KPA500.  I like the small size and weight as well
as the  slickness of  operation  with the cable option. However I have some
questions.

 

The K3 has two RF outputs and remembers which antenna to use on each band!
Very convenient.  The KPA500 only has one RF in and one RF out. So it
appears that I will have to manually switch antennas if I want to load them
with the KPA500. Is that correct?

 

I looked at the KRC2 but do not see any RF in and out connections.  How do I
use it to physically switch antennas attached to the KPA500?

 

Will the KATU500 solve my problems, if indeed I have a problem?

 

I am thinking that if I still have to do manual switching, I can buy a 1200
watt or higher amp on eBay and save money and get more power.   I have found
that power helps and more power helps more!  

 

Thanks in advance for any answers or suggestions,

 

Jack, AE6GC

Hello Jack,
 
I raised similar questions in the past.  Due to size constraint of the forthcoming of KAT500, I was given to understand that it would come with one RF input and two RF outputs.
 
Most hams have more than one radios.  Extra cabling will be required if the KPA500 is going to share among two or more radios.
 
I am not going to drag on this issue because it would come up with all the ideas of remote antenna selection, manufacture costs for extra RF input and output etc etc.
 
I would patiently wait for the final outcome of KAT500 before my decision on the KPA500+KAT500 compo.

TNX & 73,

Jack,

The KAT500 is supposed to have 2 (or possibly more) antenna outputs.
In the meantime, you may have to switch antennas manually.

The KRC2 can switch antennas on a per band basis, and may help in your
antenna selection scheme.
No RF flows through the KRC3 - it provides voltage (or a ground) for
your antenna relays.
Those relays are not part of the KRC2.
