Nevermind - I have it hooked between the radio and tuner. At one point I had
pulled the tuner out to just test the radio to antenna when I was seeing the
really low power. It was a long weekend at work and I'm still recovering.

I wanted to see what the SWR measurement and reflected power was showing
between the tuner and antenna since I knew there was some mismatch there and
validate what my antenna analyzer was showing.

I must admit to a bit of confusion as to why the SWR meter was placed between
the tuner and the antenna. ???Normally, it would be between the tuner and the
radio to show the SWR being presented to the radio.

Chad,
Are you driving a 50 ohm dummy load? It would be best to do so.
Are you confident that your watt/SWR meter is correctt at HF freqs?
When testing like this, having known references for test gear is important.

Wanted to thank you all for your help so far and taking the time to reply.
I’m working this weekend and this week looks rainy but I’ll try to move the
tuner out there since it’s battery powered and give it a try. I like the idea

What kind of radial field did you put down for the 6BTV? You should
also be ab;e to adjust the antenna for each band for a fairly low SWR
where you don't need an antenna match

Any chance of moving the tuner to the feedpoint? With the tuner in the shack,
it's making the match on the across the coax from where the mismatch actually
is - at the antenna feedpoint - and you'll still be facing some coax loss.

Here's something I learned from some more experienced operators a while
back. If you are using a tuner, then ground it. If the tuner is already
grounded, then check your ground connections.

I built the 40/80 dipole to be NVIS sine the verticals in more of a DX antenna.
To add more detail I have 48 radials on the 6btv.

Keep experiencing. I bet somebody in BVARC will come thru with help.
I have an off-center fed dipole about 135 ft. total length up about 12 ft. in
the back yard… I’m near N. Eldridge Pkw and Tanner. My signal into the BVARC
HF Wednesday net is minimal but I usually get checked in.
I’ve been a Ham since 2017 and have an 857d. Running a multi fan dipole from
2017 until I had to cut the tree down it was in in 2019 I had dismal contacts
with anyone on 80, 40, and 20.
Covid gave me some time to be at home and I setup a Hustler 6BT and have it
tuned with my MFJ 269c. I
