Yepme too. I got everything at Lowes.tools and all. One small thing. The correct part number is SNS1P6U-50R. The writing is small and Hank had a 5 in place of the second S. Also...the color of the connector indicates what coax is supposed to be used. Red is the correct color in this

Hi Jeff, I have been using Commscope F660BEF flooded RG6 for years. I direct bury it. It has a PE jacket. It is used for all receive antenna feedlines. Also use it on 80M. Crimp on F-connectors is the way to go. If you do it right it is very difficult to pull off the connector. Wedge it I a vise

I installed buryflex along with direct burial control cables last year.  I learned that it is best to directly bury the cables without conduit.  Water from condensation will eventually fill the conduit even if rain doesn't get in.  Possibly a different story in low humidity areas, I suppose,

It's really dangerous to make these "all" statements. I've been keeping rainfall numbers and reporting them to rainlog.org for 11 years.  My last measurable rain was 0.02 inches on Sept 14. The total for this year is 7.74 inches.  If I want my conduit filled with water I need to use a garden

Hi John, Never use PVC drain pipe to bury coax or other cable, the molecules are that far apart that water eventually gets in no matter what. Better to use the same pipe your water supplier uses to get the water to your house, think its Polypropylene or something like that. That pipe will not let

I installed 4 runs of BuryFlex through my slab and then out into the backyard about 15-years ago (when we built a new house) and it is still working fine. I have conduit through the slab (open at both ends) but the cable is direct buried out in the yard (about 24" deep). ---

must have to do with the annual rainfall. I too come from 30+ years in telco and radio comm. There are 12 runs of 6 in conduit between building on one campus, and a number of others around that are still dry after being there for 20+ years. And the conduit, I am speaking of is PVC TUBE..

John, Although I didn't look up F1160 BEF, if it's basically flooded RG-6 (and therefore suitable for direct burial) then Just Do It! ;-) I use Commscope F6 dual- and quad-shield flooded coax at my QTH. It's the electrical equivalent of RG-6 coax with aluminum shielding and a copper-clad 18 AWG

The answer to a lot of these either/or station wiring quandaries on RX/TX/RX transitions is a slow-relay assert-TX signal. This is a signal that would properly drive the frame relay RX/TX/RX in an un-QSK'd AL1200. This is available in any WinKey or WinKey based device like MicroHam. In contest

I discovered my rx antennas worked much better if my tx antenna was completely disconnected from the station. Most coaxial relays or T/R switches only break the center conductor. That's not good enough. There has to be a complete disconnection which I provided by using an open frame relay

I agree with Ken, with only one option, and that would be if the conduit is open on both ends.. allowing free air flow thru. That situation, MAY help dry the water from sitting on the cable, depending on the average humidity at the underground temp. Warm air from inside.. to cold air outside
