I'm looking to set up a wire dipole for 40 meters however have an interesting problem. We certainly have the space and structures to put together some rather large wire antennas. The issue is the ele
Thank you all for taking time to respond. I think I'll incorporate a couple of suggestions. It looks like a properly installed commercial arrestor alone should provide the protection I need. In addit
Yes, thank you guys for this info. I wasn't even aware copper clad steel ladder line was an option. I've been looking a ladder line based dipoles today and I think this is the way I'll go. It took me
Using insulated wire is certainly an option. This is the first HF antenna I've put up so I'm just beginning to explore what is available in terms of materials. The use of insulated wire begs a couple
Does Krylon affect the characteristics of the antenna? I've heard conflicting information about this but have not personally done a "before and after" antenna analysis. Anyone? -Jeff KE7FRJ ________
What is recommended in a climate where it rains 9 months out of the year on a site that is very close to being classified as a wetland area? The soil here is sopping wet most of the year and no amoun
I'm looking to do some runs of 9913 flex: a run from my shack to the roof (through the attic) for VHF/UHF and another run (likely through conduit) to an HF wire antenna in the pasture. Until now, mos
Currently I'm running coax right on the ground between my station and antennas. I'm looking to install some conduit so I can bury multiple runs. When installing conduit I've seen suggestions to put a
Thank you to everyone who responded to my question about terminating Belden 9913 Flex. It's clear to me now that the center conductor is larger than other RG-8 type coax. -Jeff KE7FRJ _______________
Thanks to the folks who have responded to this. Without excavating an acre or so of pasture and putting together an elaborate drainage system, the conduit I run will be below the water line most of t
Thanks again to everyone who sent me info on-list and off. I called up Davis RF to get their take on coaxial cable in standing water. I explained the situation as cable buried in a conduit with stand
Looking at the Alpha Delta coax switches, I see the "Application Information" notes that the switch can be used with two receivers and one antenna. The use of two *transceivers* with one antenna is c
When using a coax switch to make one antenna accessible to two transceivers, is it OK to use the switch between the a *tuner* and the antenna? In other words, can I use it if I have high SWR? As an e
Don, Thank you very much for the info. One more question if you will... I would like to use a switch specifically on a non-resonant antenna between the tuner and the antenna. My power would be limite
Has anyone had significant problems running coax through an attic that gets hot in the summer? I've read of problems such as the center conductor migrating through the dielectric with prolonged expos
I'm looking to put up a 28' bracketed Rohn 25 tower for some VHF/UHF antennas. There is definitely an ample supply of used tower sections, house brackets, top sections, etc. in good to excellent cond
Thank you to everyone who has emailed me on and off list. Thanks for all of the great references as well. I guess my main question is why does virtually nobody sell the self-supporting base plate? Do
A BPH25G would work fine however I don't believe a BPC25G would. Rohn's sheet on bracketed towers [1] specifically says "Pinned Bases Must Not Be Used". [1] http://www.radiancorp.com/ROHNNET/rohnnet2
Thank you for responding to this, Gerald. I was going to call you folks this week to see if you folks could shed any light on this. Radian doesn't publish specific dimensions (that I know of) on the
Stucco isn't particularly common in my area. What is the proper way to attach a house bracket to a building with stucco siding? This is cement stucco over metal lathing -- not EIFS. Of course, follow
