[SJDXA] Work Party Summary

[Bob Schenck N2OO]

A summary follows:

 

Report on things other than in the marsh:

 

 Vertical Dipole: Feedline and coil traps connected.  Untested

 

 Beverages: Feedlines run and boxes connected to all but the West. 

Left West unconnected until configuation determined, 1 element or 2.

 

Some deadfall was removed from a few of the antennae, Thanks Lance.

 

We will have to revisit most and provide some new ground counterpoise's and
a few new sta-kons to the wires as mother nature has done her dirty deed.

 

All computers are functional. One has a noisy fan, will replace next trip.

 

The Sloper switch box is a little banged up, I have it here to rework it.

 

Everything else looke to be in order.

 

Thanks for climbing today HM. 

 

And of course thanks to the marsh rats for their fine effort. K2TW, W2CG,
and of course, The Good GD.

 

(think I'll get one for that, or will I have to wait in the pileups too? )

 

           DaNO....W2NO

 

 

Report from the Marsh.

 

First, the high tide was at least 2.5 hours after the Manahawkin Bay high
tide!

 

Loop:

The loop (white wire) was cut to be per K2TW's optimized dimensions.  We
raised it to have the apex down about 30 feet from the pulley.  The bottom
corners are now about 8-10 feet above the ground.  Distance from the tower
is about 10 feet.  All this is per what was in the model.

 

NE Sloper:

Marty set the screw-in anchor provided by N2OO about 15 feet beyond the old
anchor.  We re-built the NE sloper -- the wires were cut for 135 feet.
About two feet was folded back on the top leg.  We installed the NE sloper
pretty much according to the model data.  The top is loer than the loop apex
and is about 20 feet from the plane of the loop.  The bottom leg does NOT
cross the loop any more.  The lower half of the sloper is secured to an
unused ground rod.  We'll probably need a stake to raise that up a couple of
feet in case of snow.  A quick check of resonance showed around 1.725 MHz.
We'll need to significantly trim once  we put in the lower stake.

 

W Sloper:

We re-built the W sloper -- the wires were also cut for 135 feet.  About 2
feet was folded back on the top leg.  We tried to set the top of the W
sloper at the same height as the NE sloper  and about 10 feet from the
tower.  We used the exisiting anchor rope into the woods for the center
insulator.  The geometry of this antenna is not per the model.  We really
need to pull the anchor rope to the center insulator but first we need to
find the end in the woods!  The lower leg does not cross the loop, but goes
past the tower.  A quick check of resonance showed approximately 1.710 MHz.
Way to long right now, but it makes no sense to do anything until we fix the
geometry.  ONE SUGGESTION:  lower the W sloper and connect the anchor rope
to the center insulator as far pout as we can and then raise the antenna.
This should buy us some distance.  We may need to raise the upper end a few
feet to help raise the lower end.

 

Vertical Dipole:

 

I don't know status of connections.  Can someone confirm?

 

Receive antennas:

 

I believe all beverages were walked, boxes connected and feeedlines run back
to the shack. (Can someone confirm?)

 

We did not find the short receiving vertical in the shed.  Marty is going to
check his shed to see if it's there.

NOTE:

I will check the vertical dipole next time I am at the shack.

 

I have more of those screw anchors if you need/want one for the SW sloper.
Just holler. Might make that antenna easier to deal with and make it
somewhat symmetrical to the NE sloper. Using the tree can present problems
in the dead of the winter???

 

Beverages still need to be walked. I believe that the righthand NE beverage
was walked by Lance. Not sure about the lefthand one. The West was walked by
Kevin and Steve.  I think NW, N/S, SW may need to be walked.

 

Also, there are some unused wires left around the WEST beverage.. As well as
a staggered element. We should remove anything not used. Getting confusing
out there.

 

The receiving vertical coax was not run. Hopefully Marty will locate the
vertical in his shed. Lance and I do not remember seeing it over the past
year in the on-site shed.

 

 

See ya' in the Pileups!
