LMR-240 looks like a good low loss coax, lower than the RG-8X I have today. This kit is an improvement over our standard HF transceiver RFI Kit and now includes our very effective Coax Noise Filter, (CMNF-500-50) to reduce common mode noise picked up by the antenna feed line coax as At HF frequencies (even 10M), 200' really isn't that long a run where coax loss is that significant. The post explains why high quality heavy shielded coax Using these, you know you are doing your best to minimize loss, ensure solid switching and are getting the best isolation. (75 feet) max. But most coax types have a limited bending radius (25 mm onetime bending for RG-58). Longer runs, or primarily VHF/UHF operation, LMR400 is RG-213 is the best of the coax mentioned for a 50ft run and by a lot depending on frequency range. If you switched to fancier coax such as LMR-400, the loss for 100 feet of coax would be 2. For example, on a run that is less than 100 feet, RG-58 (U) provides a good balance between price and performance for HF Frequencies. - The two coaxial cables in question are both 25′ in length and both are equipped with BNC male connectors on each end. It's ugly yet it worked beautifully, in that it solved the common mode problem I had with an end-fed antenna. I then measured a short cable with a very low loss, a 1 m / 3.

Having a half-wavelength of wire in the air for an antenna is really the best way to start. It has an incredible construction tha We recommend looking at the Coaxial Cable Loss Chart to determine what coax to use. I use RG-58 for all my HF antennas, since it's light, flexible, convenient, and cheap. Can you use them for switching a radio as well as an antenna? SPOILER - yes, yes you can. Ultraflex might be ok, but ugh, you're only running <20 feet max and the loss differential between it and LMR240 is so small at those lengths to be negligible and not worth the engineering frustration. 96 out of 5 stars Estimated Ship Date: Today ViewLoading Today 4. UHF - PL-259 - Male Crimp / Solder For LMR-400 / RG-8 Teflon On HF with runs under 100 feet, that area is not usually the feedline unless your point of reference is exceptionally low-quality coax. Most coax is either 50 ohms or 75 ohms. In testing the swr with the counterpoise attached, 10 and 12 meters are rather good, but from 15, 17, 20, and 40 meters, the swr was too high. What coax do you recommend for a gmrs repeater. Use the highest frequency you use as what type you need. I'm planning to use this coax line for HF (recently upgraded to General!). $4. With an HF antenna you either have a lot of wire in the air, or on the ground depending on what style you choose. STEREN 205-700 Coax Cable Connector With a length of 100 feet, this coax cable is suitable even for high-powered applications. But there is another variant that is very effective on the ham radio HF bands. Which is best RG-213/U or LL400? The LL400 you have appears less loss than 213 and is slightly less, which surprised me. Winding it tightly may very well damage the coax. Belden RG-8X is very nice coax for HF use. I think, over the years my best HF antenna was a 80 meter dipole with a 40 meter inverted vee both fed at a common feed point with a single coax.
