KPA500 Multiple Antenna Option

I'd love to see the KPA500 companion Antenna Tuner have a minimum of 5
antenna outputs which can be controlled automatically via the K3. This is the
only way I'd purchase a KPA500 as otherwise I'll keep my Quadra which does
automatic bandswitching nicely with the K3.

associates one of four antenna positions with a band, this is changeable

antenna
switch. If the remote switch is not in use, the "antenna" which is
associated by band is irrelevant. I am surprised that the KPA500 does not
have this capability standard and built in with the outboard remote
antenna
relay being an option. Without this, band changing is not, in fact,
automatic.

] KPA500 Multiple Antenna Option

Hello Dick,

I think it is very common that many of us have more than one radio and one antenna. Multiple antenna output and input sockets are just a logical customer's wish.

I hope the forthcoming KAT500 will address this issue. Otherwise, I am afraid I have to go for the others such as SPE

Re: ] KPA500 Multiple Antenna Option

Sorry to say this but when is enough, enough?....the KPA-500 will come in
both desktop and remote versions, it will have balanced AND unbalanced
antenna connections...I now wonder when someone will ask for 10 of each?

To simply keep adding numerical options drive the price up for all
customers. I certainly don't require more than 4 antennas but I appreciate
some folks have 10 or more to play with and several radio to boot.

But they are NOT the vast majority of Elecraft customers I would guess.

I think a search of the archives may reveal that the KAT-500 will have 3
antenna connections and one is for single wire or open wire feedline. I am
going from memory and we all know how dangerous that can be...:-)

One other comment I would make is that IF I had a Quadra I cannot think why
I would buy a KPA-500....unles it does not do 6M maybe?...not sure what
Yucksu provide...:-)

KPA500 Multiple Antenna Option

Hello Gary,

Yes, all I needed are just 2 RF inputs + 3-4 RF outputs in a linear amplifier. I trust it is just a common design in most of the reputable amplfiers. Since the design of KPA500 + KAT500 is not in one box, I suppose the forthcoming KAT500 will cover this issue.

The design of KAT500 should not only couple with KPA500 but also other radios / amplifiers in a smooth manner. It is just a business sense to do so. Elecraft will just be more happy if other non K3 radio owners also buy the KPA500 and KAT500.

TNX & 73,

Johnny VR2XMC

Re: ] KPA500 Multiple Antenna Option

In reply to this post by Gary Gregory

OK Gary I see your point - but I do want KAT500 to be top notch. A decent
solution could be a few antennas inputs and outputs in the basic model and
then an add-in module with more options as I believe it to be the hardware
making more antennas expensive - I believe that the switching circuitry
being at almost the same price level for 4 or 16 antenna ports.

Antenna switching by an antenna tuner is a wonderful thing if the signal
flow also allows bypassing of the tuner for any given output. This is
how the Ten Tec 229 and 238 tuners are designed, and is one of their
most important design features (in addition to the fact that they are
excellent electrically and pretty good mechanically). That said, five
outputs and the switching for them could be tough to fit into a small
package. An important benefit of doing so would be memorized settings
per antenna per band.
