Re: Re: [Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry

Nate,

All enviorments have their qurks.  We all can find stories of an antenna that 
got smoked.

However, here with the salt air and a number of folded exposed dipoles get 
eaten up with the salt air.  This aint one, but a number of them.  Now we get 5 
miles from the Gulf don't have the problem although a recently removed DB224 
looked pretty sick.

I've had 3 of the dual band Diamonds and one Comet last maybe 3 years before 
lightning completed toasted and blew them apart.  They aint much of an antenna 
when it comes to construction with what looks like getar wire as a coil and 
cheap caps.  2 were low, 30 ft and 2 at 100 or so ft.  All were top mounted.  
They do work well as antenna and don't cost $600, but would never put one at 
1175 ft.

I've seen fiber glass antennas, commerical like the super station master, last 
for 20 years in large substained bitter cold winds with small show of 
errotion?.  This is common for them.

All antennas have their pluses and minuses and one has to choice based on their 
situation like anything.

Up here, above 10,000 MSL, the UV rays eat up the fiberglass and they  
don't last any longer than 10 years, either.  :-)

That is... if they aren't turned into hundreds of little fiberglass  
toothpicks by lightning, which usually gets them first.

Side-mounted with a top stabilization arm, they last about as long as  
the folded-dipole arrays.  Without a stabilization arm (top-mounted)  
they tear themselves up pretty quickly in 100 MPH+ winds at the  
mountain-tops.

Seen people here "de-fuzz" old fiberglass antennas by re-glassing  
them, hand mitts, curing time, big mess.   Not sure I'd want to mess  
with it.

I have a ham-type Comet up that's been up for about 10 years, last  
time I touched it, it has a nice layer of fiberglass "dust" on it and  
it's probably getting near the end of it's life... or past it.

It's not in repeater service, it's one of their tri-band things with

another vertical stick with a little gain for when I need something

Nate,

Yep 10 years is long time and mother nature really does whatever she wants.

I've seen good fiberglass antennas last 20 or more years in harsh enviroments 
and still show much life left.

I think anything metal or antenna elements exposed will have electrical 
problems due to damage to the connections.  Having inside something would at 
least keep out much of this.  The fiberglass radom might deterate some, but the 
electrical elements would still be intact.  Of course if there is leakage then 
the elements can get inside and do damage.

I am deffinitly not thinking of one of the Ham ventage antennas for their 
fiberglass is little more than paper, hi.

I have a 440 machine running a DB420 that is on the ocean (I mean, right on
it, like the base of the tower is less than 100 feet from water).  So far
the antenna has held up (about 5 years).  Can't say as much for the repeater
iself though.  It's a 200 watt Mastr II, and the salt air environment has
taken its toll on all of the metalwork, connectors, etc.  Keeping it on the
air has been a headache.  I've used fiberglass antennas as well as such
sites, and copper isn't all that thrilled with salt air either.

I wonder how gold anodized (alodined?) aluminum dipole arrays would survive,
such as those TX-RX sells.

Have you looked at the heavy-duty Sinclair folded-dipoles?  They seem 
better built than the DB's.

10 years is starting to push it with just about any antenna we've used, 
though -- some make it longer, but the elements are mean to everything.

Re: RE: [Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry

[Ron Wright]

Paul,

I have a DB224 at 1175 ft above ground 1/2 mile from the Gulf of Mexico here in 
FL.  Put up in 1996 and it is having serious problems, 2:1 SWR on the ground.  
Think it is the salt air.  The connections, on antenna and connectors, were 
coated and sealed before install.  Other services with exposed dipoles have had 
the same problem here.

We have same antennas about 5 miles from the Gulf that last for years although 
none past 20 years.  Have seen about 5 of these replaced recently, most VHF.

When I replace my DB224 I am going to a SuperStation Master fiber glass pole.  
It is obvious the exposed dipoles have a survival problem in this salt air.

I know what you mean about the fiber poles and lightning due to the soldering 
connections.  If top mounted would be reluctant, but have seen these last over 
20 years and still had plenty of life in them in some harsh enviorments.

I like the DB224 with it squeeing of the pattern, but exposed dipoles can have 
problems.  Same with towers up north with ice falling off a tower.

RE: [Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry

[Paul Finch]

If aluminum were banned from most sites there would not be many systems on
the air.  It’s only when dissimilar metals are joined that you have a
problem and that’s a very easy fix.  I may think twice about using a
aluminum antenna in a high humidity/salt area these days but I doubt it.
Way to many DB Products out there that are working well and stand up a lot
better to lightning than fiberglass radome antennas do.  You just have to
know how to prepare the aluminum antennas before putting them in the air.  I
know if a DB-410 that I put in the air in 1975, it was used when I got it.
It’s still in service today and working well.

 

I have several DB style folded dipole antennas on my commercial sites
without any problems.

Yes, aluminum corrodes very rapidly and goes from being a good conductor to
being a terrible one.  FOr this reason very special precautions must be
taken in the preparation of connections to it and protection form anything
that would compromise it over time (such as moisture or contamination).

Along with that question, is the banned aluminum coax the old unjacketed 
stuff like the CATV folks use, or is that any aluminum coax?  I'm thinking 
about the construction of Commscope cable that was used extensively by the 
cellular carriers a few years ago.  It was a jacketed aluminum construction 
if memory serves, the jacket and the foam were practically glued to the 
inner and outer conductors.  I wonder if this is what Andrews has up their 
sleeve.

One group for years used a 5-conductor twist-lock for 120vAC
(4 conductors - ground, neutral and two hot circuits) and the
extra conductor was attached to a relay in the building alarm
box.
The 120v kept the fridge cold, the battery up, the AC lighting
circuits hot. The alarm lead in the connector was just 120v fed
back from the trailer to the relay coil. When the AC went away,
the relay dropped out and the alarm circuit was activated by
the contacts opening.
There were a number of things that could drop that AC
voltage... a door opening, under or over temperature, and more.
The under/over temperature sensor was simply a standard dual
tipping mercury bulb air conditioning thermostat, one that had
both limits set a little further in the extremes than would be
considered comfortable (i.e. the low end switched on at about
38 degrees and the high end switched on at about 100 degrees).
Either one was considered a temperature alarm.

Since the connector was simply a large twist lock, and the cord
looked like a fat outdoor-grade AC cord, nobody had any inkling
that the cord had an alarm circuit in it as well as power

Just though I'd toss an idea out there...

Re: [Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry

[Eric Lemmon]

I just looked at the Andrew spec sheet for AVA5-50, which is the "Andrew
Virtual Air" replacement for LDF5-50, and the two cables appear to
identical.  The AVA5-50 has a copper tube inner conductor and a corrugated
copper outer conductor.  I suspect that the thickness of both inner and
outer conductors has been reduced, which accounts for the lighter weight,
but there is no aluminum involved.

It appears the "Heliax AL" is the aluminum version of Heliax LDF5-50.  As
Jesse pointed out, the smaller Heliax sizes such as LDF2 and LDF4 do use a
copper-clad solid aluminum center conductor.  Larger sizes have hollow
copper tubes as center conductors.

I think the price of aluminum is up enough also to
make it worth while to scrap.  I have heard of reports
of aluminum siding being ripped off.

I have had a 125 Ft. of Andrews
LDF 450 ½ in On My 444.75 Repeater for over 15 Yrs. it actually got
bent a little during a Move I put 3 Popsicle Sticks on it and Tape SWR
Is Still 1.1  ,  I just wonder if they Switch to alum if it will cause
some kind of reaction of Dissimilar Metals on the Connectors , Oh I
know what they will do Drop the price of the Coax and raise the Price
of special connectors .



Happy Repeater Building

Damn, I assume that the connectors aren't the same, then?

Our stash of LDF5 connectors is going to be worthless after a time... if 
that's the case.

Perhaps they should mark the jacket with 'Contains no copper' to
deture cell site theft as well.

[Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry

[skipp025]

The Wal Mart effect* makes it to the Communications Feed-Line industry 
(*Global Economy) 

enjoy,

Building upon the market success of its two most significant cable 
products, Andrew Corporation has announced they will be streamlining 
its long-running and market-leading HELIAX� product portfolio by 
discontinuing its LDF series cable and featuring alternative products 
that offer higher value.

Andrew will cease regular production of LDF5 and LDF7 series coaxial 
cables on December 31, 2007  with equivalently sized HELIAX Andrew 
Virtual Air� (AVA�) and HELIAX AL aluminum series cables serving as 
direct replacements.
