To the best of my knowledge, Hi-Z and DX Engineering are still tied up in 
litigation over intellectual property rights regarding RX antenna design. 
Hopefully it will get worked out and Lee can resume building his excellent 
products.

Hi Brian, HI-Zantennas is in the middle of a lawsuit and I believe sales 
have been temporarily suspended.  I'm a satisfied customer of HI-Z antennas 
and as soon as they get back in service I'm sure the website will resume. It 
is frustrating for many of their existing customers as well as potiential 
new customers.  Stay tuned for new developments.....  73 de W7JW

Hello Dick and Lee,

Glad that all problems worked out and you all are up and running.

My 4sq receive array is working fine.  It has equaled or surpassed all 
aspects and expectations that I had expected of this receive array.

Looking forward to the next design improvements and all futur advancements 
to help us layman improve our receive abilities on 16 and 80 meters.

Great to have you back,

Patrick, W4PV

It's great to see Lee and Dick back in business!  Great products, great support, and good prices.  Has anyone come up with a good long term solution for weatherproofing the amplifier units at the antenna elements?  Last December when it was cold and I was installing my 8 circle 160m array, I wrapped the amps in plastic grocery bags and taped them up.  While they've held up surprisingly well, I need to implement a permanent solution which doesn't introduce excessive C between the antenna and ground leads on the amps.  Any ideas?

Hi Dave...

My antennas came with a length of tubing and cap.  See:

http://www.hizantennas.com/hiz_verticals.htm

The thing I don't like about this arrangement is that the feedline is forced to
make a sharp 180 degree turn when the preamp is inserted into the tube.
With foam dielectric coax this could be a problem over time.

73, Roger

Dave, I use plastic coffee cans. I'm basically lazy and just invert the cans 
over the preamp and tape them to the post holding the vertical. The plastic 
is easy to cut to allow cable ingress and egress.  I leave the bottom of the 
can open. I have found over the years in Ohio that humidity does the most 
damage and sealing anything results in corrosion. So now I leave everything 
open and covered from the rain or snow. The coffee can preamps were buried 
in snow and have been rained on heavily with no ill effects so far. I need 
to do a Spring inspection soon.

I do use decafe cans so the preamps don't get too 'excited' whilst catching 
DX on 160 and 80!

I put up an 8 circle-narrow 160m array early last December.  I was in a quandary as to how to weatherproof the amps at the antenna elements.  Being pressed for time and having a snowstorm bearing down on me, I wrapped the amps in plastic grocery bags and secured the mess with tape.  And it was a mess but it kept things dry, or so I thought.  I had not given consideration to condensation.  Cal, W0IZL, mentioned to me that he used the same approach and had experienced enough condensation problems that a couple of his amp boxes had to have work.  I felt more pressed to find a more permanent, suitable solution that would allow for air circulation. 

In my pondering as to how to approach a more permanent solution, I put the amps inside of 4" PVC with caps on top and leaving the bottom open.  I was just going to strap the PVC to the side of my mounting pipes and bring the antenna and ground wires in through small holes in the side of the PVC.  In my discussions with Toni, N0NI, he suggested drilling a hole in the pipe cap and sliding the antenna element (in my case, 1" aluminum) through the cap with a piece of 4" PVC attached to it.  I cut the 4" PVC in 15" length and put an assembly together to try.  It works quite well.  The PVC cap rests on the screw which passes through the 1" aluminum elements and secures the antenna wire to it.  I sealed the hole in the PVC cap around the aluminum passing through it with liquid tape.  The PVC pipe covers the amp and associated wiring.  I did drill the hole in the cap somewhat off center to allow a little extra room for the amp which was is tie wrapped to the side of my steel "U" type 4' fence post.  Now that I've tried one and am pleased I'll be finishing up the other seven elements in a similar manner tomorrow (if we don't get rain or snow).

Good going.  Unless one uses a gasketed enclosure, moisture accumulation 
is a problem, unless there is a way for the accumulation to be removed 
or released.

Even gasketed enclosures are a problem.  Unless they are pressurized (like 
air Heliax), you still have problems with condensation.  Leaving an 
opportunity for some air flow is a better approach than air tight.

Dave,

Yes. I was not totally clear. There are gasketed types that have rubber 
o-ring / gaskets around the coax, too and work very well. It is true 
that when sealed they retain whatever moisture is captured, but find 
that typically is OK.

Air flow in lieu of a totally sealed approach works very well indeed.

Dick

I have had good results with small gasketed enclosures, like the one at
http://www.w0btu.com/images/Beverage_control_box_4444.jpg and
http://www.w0btu.com/images/Beverage_box4412.jpg.
I fill all the connectors with silicone dielectric compound, and there are
NO air vents. Works for me.

I don't know how big these preamps are. Regardless, the larger the
enclosure, the more of a chance you have for moist air getting inside.
Reason being, there is a larger internal pressure change with a given
temperature and/or barometric pressure change.

In the past, I have put a little desiccant package inside enclosures sealed
with tape.

Hi Mike,

Could you send the link URL for that enclosure?

Interesting. Are the vertical wires supported by horizontal wires strung 
between trees?

What did you use to insulate the vertical wire from the bolt on the ground rod?

The horz piece is rope and the pve slides over a ground rod and only one 
bolt goes through the grund road and the oter is insulated from ground.

Let me try this again.  I been up a tower all day and cannot spell.
The horz piece is rope that holds the vert up.  The pvc slides over a ground 
rod and only one
bolt goes through the ground rod and the other is insulated from ground.

You mean a URL to a supplier? I don't have a link handy, but Mouser and
Newark have them. They are made by Hammond.

They are polycarbonate, and the lids are available in clear, smoke, and
opaque. They come in many sizes. I have been using those for my Beverage
antenna enclosures for some time now.
