Best to use lengths that aren't close to a multiple of a half-wave on

Any plans soon on a legal limit (1.5 KW+) auto tuner that can handle 10:1

Just to clarify: I'm referring to *end-fed* antennas that are a
multiple of 1/2-wave. The feedpoint impedance of such antennas is
extremely high, something like 3-6 Kohms.
A 1/2-wave dipole or inverted V, fed in the middle, will typically be
50-75 ohms.

Hi,
Yes, but the cables are BNC terminated cables connected via adapters from

very expensive items, vacuum variable caps, [high current AND high voltage]

right?
Yes, the connections are as you've suggested.

interrupt the KPA500 PTT key line with just that one cable.

BNC's can handle kilowatts of RF efficiently at reasonable SWRs. After all,
the popular type N is simply a BNC with a screw-on outer shell.
Decent quality BNCs (e.g. Amphenol) are rated at 500 volts peak with a
dielectric that will handle 1,500 V rms. That's 5 KW into 50 ohms, if my
brain is
The 500 volts peak translates to 1250 watts at an SWR = 1.0, but the
1,500 V rms translates into 45 kW (also at SWR = 1.0) if my calculator
is correct. In ant case, BNC connectors do not have a problem at the
500 watt level unless the SWR is high.

I installed the Oak Hills BNC connectors in my K3 during the initial build 5
years ago. Great decision. Much more convenient and allows for rapid cable

BNCs.

It's a simple homebrew - a square of aluminum (or whatever - even scrap PCB)
with a hole for the BNC in the center and two or four holes in the SO239
pattern for mounting. But I don't know that there's a significant loss in
using a *quality* SO239-BNC adapter. That's what I do.
It's very nice
So we could expect that a newly mod'ed K3 12VDC output can supply the P3, 6M

Craig,
I do not want to push the envelope, but I have found that UHF
connectors are more reliable than BNC. The BNC connectors are smaller,
but are more susceptible to the connection being distorted because
