[SJDXA] FW: Work Party Re-schedule 11/07

I have an EZ HANG sling shot with fishing reel and weights…. Trick is to shoot the weight over the tree (monofilament line) and NOT pull it back until you remove the weight and tie on and pull a light cord back over the tree. THEN, use the light cord to pull back your permanent rope. You can’t cheat or you end up with weights hanging in the tree!  L

I loaned it out, but I need it here too so I can rebuild my 160 inverted L. So, I’ll put out the message. But K2RET also has one so we have several available here.

 

See ya' in the Pileups!

73!

Thanks for the update Bob and you, to DaNo.  I'm not sure a screw anchor wil help the W sloper situation.  To mirror the NE situation, the anchor point would need to be about 250 feet from the tower.  The tree line along the more southerly path out to the tower is closer than that.  So, we have to go over trees and getting ropes through the dense tree growth is always a problem. .  My own experience with the same types of trees here is that rope inevitably get bound in these damn pine trees.  I think we can improve the W sloper positioning by lowering the sloper completely and tieing the center insulator as far as we can out on the existing anchor rope and then raising the tower.  We just ran out of daylight Sunday to do that.  Moving the antenna will also require a trip up the tower to reposition the W sloper coax.  We do have plenty of slack in that coax.  If we can get a small crew together, we can relocate the W sloper anchor rope.  I think we can move it a little closer to the SW guys (I'll model that later this week.)  Using a bow and arrow is a problem with the dense trees.  It would be better  use a wrist rocket slingshot and (non-lead) sinker, but, of course they are illegal to use in NJ :-)

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!

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.
