Connector suppliers....

Post by waveguide » Wed Jan 24, 2018 2:26 pm

Hi,
Ok, so I generally use a combination of Spinner, Andrews and RFS connectors - but is there a cheaper alternative out there?

I'm looking to buy a stock of adapters such N to EIA 7/8, EAI 7/8 to 7/16" ect.... Stuff to get me out of a pickle!!!

Who would you recommend?
I would continue to use the premium connectors on installations, I just need some cheap generic adapters to have in an emergency!

Thanks !

SWR has a line of connectors a bit cheaper than the other boys, and I think the quality is just as good.

You might want to give this outfit a look:

There are some negative reviews but I have had good luck.
Also, ebay has connectors show up from time to time.

Some of the Andrew cables have been re-designed so that only their connectors will work with them. Believe either (or both) the newer 7/8th and 1/2 inch cables . May also need special tools to put them on.

Beware of the new Andrew cable - the copper sheath is very thin and you have to be extra careful that you don't cut through it when installing grounding kits. The center conductor is also thin and filled with foam to try to make up for the fragility of the conductors. I would stay away from it.

Ain't that the truth. The new Andrew and RFS cables rely on the outer plastic jacket for their strength. A simple score line around the thin copper shield of the newer cables will result in a broken shield if you aren't very, very careful. I hadn't heard about the foam filled center conductor prior to now.

What Andrew cable uses this foam filled center that you speak of?

The thinner copper has little to no effect on the operation of the cable UNTIL it is damaged.

I believe that the OP may be looking more for interseries and intersize adapters than coaxial connectors.

I keep an eye on Ebay as various EIA size to size and EIA to N adapters occasionally show up at very attractive prices.

I have one of those kits of "make our own interseries adapters" that has proven priceless in a number of situations. They may not sweep 100% perfectly but they will get you back on the air in an emergency.

The cable is AVA5-50FX. According to the Commscope website, this cable is not available in the US and Canada, but it showed up at my project several years ago.

As I recall AVA5-50 is a hollow center conductor anyway. Was the FX foam filled version center conductor even thinner than the normal AVA?

I have installed quite a bit of AVA cable and must say that although it seems to work OK, I am underwhelmed with it's physical strength.

I needed some 7/8 diam and 1 1/4 diam Heliax type cables a couple of weeks ago.

I was having trouble with Commscope having obsoleted several of the connectors we needed like 7/8 EIA and 7/16 DIN for the new AVA5 and AVA6.

The folks at RF Parts recommended a Heliax type cable from a company called Eupen. They stock both the cablea and connectors. RF Parts highly recommended them. Eupen does seem to have a complete line of connectors available and the cost is similar to Commscope.

This is a shame as at one time Andrew cable and other products were top drawer. Now that Commscope has taken over a lot of stuff has gone downhill. Really cheap of them to discontinue the printed catalog and the on line catalog is terrible and hard to use.

Kinda interesting about the "new" Andrew stuff. " Back in the day" when I were a salesman, I stopped at a job site where a tower crew was putting connectors on some 3 1/8" air dielectric Cablewave I sold for the project. I took a look at the open end and saw that the copper outer was noticeably thinner than equal Andrew line, and Cablewave's neoprene jacket was much thicker than Andrew's. That's when I figured out why so many of their cables got dented in shipment, or were easily bent. Andrew then was much huskier.

Sorry to hear that the new owners have changed the product that severely. Thanks for the reports.

I believe ERI owns Andrew, and the coax used by the cell industry is somewhat thinner.

ERI only owns the broadcast transmission division.

The microwave side is owned by CommScope. They may also be the ones making the coax/waveguide as well for them.

The satellite side is owned by another company, who's name escapes me now. They don't offer support of the old antennas, unless you pull teeth.
