[Fourlanders] 1/2" hardline

[Rogers, Ron]

Well Tom, 

There's a difference between the rib spacing on Andrew Superflex, verses Andrew LDF4-50, the "standard" of Andrew 1/2" Heliax.  

And the connectors are different. From what I remember the last time I saw a length of SucoFeed, the rib spacing looked to be similar to LDF4-50, but it was a long time I ago that I saw it.

There were bunches of LDF4-50 and LDF5-50 for sale at Lawrenceville Hamfest.

   Ron,

 Thanks for the info...that helps.

 The reason I asked was that this stuff can be purchased, new, from The
Wireman for 1/2 of the cost ($1.20/ft) compared to Andrews ($2.50 quoted
today) new. According to The Wireman, the specifications for 1/2" seem to be
very close, up to about 1 gig, then Andrews looks better. I'm aware that
Andrews can be had at about $1/ft new "when you can find it", but I've been
looking since Shelby and have had 3 strike-outs so I'm just going to bite
the bullet and go with Sucofeed, especially after your comment about
Huber-Suhner's reputation. My 2 mtr station has been sitting through the
last  4 or 5 openings now, for lack of a transmission line, and I'm starting
to get grumpy :0)

 The station only requires a run of 70' and the loss on Sucofeed is supposed
to be .9db per 100' at 400mhz so I feel pretty comfortable using it since I
don't intend to be QRO above 70 cm.

 From my discussion with The Wireman people, I think I can use the same
connectors from Super-flex, which I happen to have. If they don't fit as is,
I'll turn them out on my lathe.

 Thanks Ron

Not really, but I do know it is made by Huber-Suhner, which is a reputable
name.

However, most of us "professionals" prefer Andrew cable and connectors due
to the availability and cost effective pricing on the cable itself and the
matching connectors. Not sure if Sucofeed and Andrew feedline can use each
other's connectors.

Sometimes what can be saved on cable cost is offset by the price of "rare"
or pricy connectors.

 Hello to all,

 I just heard about 50 ohm 1/2" hardline called "Sucofeed" which is sold by
The Wireman. Does anyone have any experience with this product?
