Sorry if this doubles, but 12 hours after I post my first reply it
still wasn't up. The 1505A was "free". My friend is on long term disabiltiy insurance. His interests are fairly limited at this time. He wants to monitor the FD that he worked in for 20+ years and they have gone to trunking. I would have gladly bought him the correct cable, but his is very stuffy about charity. He is OK with helping others, but has a very difficult time accepting if from others. Between he and his wifes saving, the procceds from the sale of ther fancy home, and money saved by movcing to a much smaller town ~20 miles away from Lexington, they get by in a fairly comfortable life style. His brother found a NRD525? in what appears to be mint condition. His wife found a Pro2067 at a flea market for next to nothing. The Radio Shack diskcone was sitting in another friends collecting dust. He dropped out of scanning 15+ years ago. The Belden PDF spec sheet for 1505A says that the black is suitable for exterior use. If his scanning interest grow, and the need arrises I am for certain going to put better, as in lower loss, cable up. But for now, he has a very effective HF and VHF/UHF monitoring station. Apparently I didn't make my primary reason for point clear: 50 Ohm RG-59 is not the only good choice for scanning or SWL. "F" fittings are a good and inexpensive alternative to BNC connectors. And by using "F" "static"/ground blocks where the coax enters the dwelling, one can meet the requirement of the NEC to "..ground the outer conductor before the coax cable enters.." And that a little scrounging can greatly reduce the cash outlay for a beginner, or for an experimenter. I installed a coaxial dipole using the 1505A for feedline. "F" fittings all the way to my IC28A. SWR, 1.5:1. I can bring up a usefull number of repeaters. And on my ancient Pro2004 I can hear PD/FD/PS comms out to maybe 50 miles. My friend has a general class ticket, but has been inactive for a LONG time. I am going to do a test and see if we can reach each other simplex. I am loaning him the antenna and an acient Clegg @mTR FM rig. Just for grins I tossed a 10mtr coaxial dipole, again fed with 1505A, and was pretty well shocked by how well it works. Talked to a mobile in GA early this afternoon. Even with near 0 sunspots 10Mtrs opens up every now and then. Now to see if I can trade a HTX100 from a friend who has left radio for the lure of evercrack. (EverQuest) He plays 30+ hours a week, and works a 40 hour work week! I wasn't trying to say, or claim that 1505A is great cable. At it's inflated price it is far from a bargin. But as you point out there are other, low and very low loss RG59/RG-6 75 Ohm coax available. But for free it is one hell of a bargin. And I suspect that even you will admit that given his listening target, and antenna, better calbe wouldn't have given him better reception. After all, full quiting is hard to improve up on. I don't know if it is practical to think of trying to monitor trunked mobiles directly, and at his distance I doubt if heliax would help. Terry |
