The maximum usable frequency (MUF) is the highest frequency that, with a probability of 50 of the time, can be used for radio communication between two points at a specified distance (but not necessary in all directions) via refraction by the ionosphere. For strictly a non-commerical "monitoring" set up, you really don&39;t need to worry about coax loss at HF frequencies. It would shorten it by 25 feet and it is slightly bigger cable. 4 dB less than RG8X. P preservedkillick Registered Joined Feb 6, 2008. DRF-400 is equivalent to Times LMR-400. Apply the liquid tape on the exposed end of the pigtail to seal it against ingress of rain water. 3333 feet of coax. This MPD Digital RG8X marine coax is certainly a better cable for UHF VHF RF AIS radio while flexible enough with good signal retention. However, you may find that your mono band delta loop may tune up on it&39;s second harmonic at a higher frequency eg. This also changes with frequency so while the numbers I have provided are good for 2m (145mhz), they change for what is considered HF radio. WARNING To avoid problems, a dipole antenna should be a at least 55 feet above ground. My trusty MFJ-259 assures me that it is not very good for VHF use, but I have external antennas only for HF, and in my house I needed to make some bends that are below the recommended minimum bend radius of. Is rg8x good for hf. Only marginally more expensive. Best Coax for Ham Radio Reviews. for your purpose. The center conductor was used as the radiating element and the braid as the ground plane. Two are selling for 20 each and the other is a 10-20-40-80 meters fan dipole for 25. It would shorten it by 25 feet and it is slightly bigger cable. Note Coax losses shown above are for 100 feet lengths. The mix used will determine the best choking impedance for the desired frequency range. This coaxial cable is a wise investment at a low price for long-term use on the ocean to pick up marine signals. Changing the able to RG-8X drops the loss to 4. 8-61 MHz) The simplest, most cost effective feed line choke is a ferrite ring installed as shown in the picture (at the antenna feed point). This makes it suitable for many applications, even where you have to run it in tight places. DRF-400 is equivalent to Times LMR-400. It is more expensive, but you get what you pay for. I use either 100m of CRT France RG58 CU with M1728 stamp (exact same cable found on Sirio mag bases) and Mil-C-17f stamp or 2x100m (328 ft) military surplus ITCBELDEN RG223 with a M1784 stamp that is.

This PL-259 (UHF-Male) connector is constructed of silver plated brass and it fits LMR600 coaxial cable. 21 at 146MHz at a radiator length of 1195mm - thus confirming the actual length correction factor was close to 93 for my construction technique. Delta Loops for HF "You&x27;ll love lower noise and relative gain over a dipole&x27;s ears". A magnifying glass. 5 is 4. I know there are those that obsess over losses, but even the largest difference between the coax types shown in the 70 cm ham band won&39;t make. 2 dB at 400 MHz & above at 100 feet. Feb 24, 2014 Personally I use RG-214 or RG-214 for my HF applications. Improves antenna pattern by preventing your dipole from becoming a tripole Prevents pesky coax braid radiation and RFI for best results use multiple turns through center Use one choke for each antenna feed line. See the attached picture for the braid quality which is better than most of the cheap Chinese cables. They are one of the most popular choices and most easy to come by. Stations all over the Midwest, South and Northeast. The antenna is tuned for UHF and is very wideband an swr of 1. also if put on power cords of noise devices. 8-61 MHz) The simplest, most cost effective feed line choke is a ferrite ring installed as shown in the picture (at the antenna feed point). MPD Digital LMR400 (35ft) - Best Heavy Duty Coax For HF Ham Radio; 03. But it&39;s a poly dielectric, so a fraction of the cost of Teflon. Great for rg8x or rg58 choke on hf frequency. OCF HF dipole, but for most other balun applications, a simple coiled-coax 11 choke balun works very well. 3 Ft RG8U Coax CB Ham Radio Cable. If it&39;s real RG8X and not some Chinese knockoff, yes it will easily handle 600 watts on HF. Weatherproof it and it is fine. Mar 13, 2019 LMR 240 is RG8X size wise just as LMR 400 is RG8. I like it as an all around cable for anything HF-UHF and potentially higher.

CABLE XPERTS RG8X (MINI 8) wPL259 CONNECTORS MTC08XC1. The best material for HF common mode chokes, in my opinion. Enclose in a watertight box with SO-239s on each end to simplify most aspects of insertion into existing feedlines. The cable&x27;s hand-soldered, quality PL-259 ends. Useful for small cables or one pass with RG8 size coax (43, 31, and 61 beads). Reviews 14. For VHFUHF you need less loss. My SWR testing on the second harmonics showed RF and SWR needles swinging up and down together which usually isn&39;t a good indication of an efficient antenna. It&39;s double shielded, just like the Teflon stuff. RG-8X is easier to pull through conduit and route through a basement or attic than RG-8, and outperforms good old RG-58 by a wide margin. Watch the subsequent episodes for more information about coax. voltage can easily become high enough to break down the foam dielectric. Coax for Ham Radio Buying Guide. On the other hand, if you&39;re running 200 ft to a tri-bander on a tower, that smaller coax would burn more than half of your transmitter&39;s power on 15M and. - For portability RG58 or RG8X may be best (lighter, thinner and more flexible). 5 feet of the RG8X coaxial transmission line feeding your ham radio dipole. Watch the subsequent episodes for more information about coax. It would shorten it by 25 feet and it is slightly bigger cable. Mixes 31 and 43 are best for HF use (31 is better for the low bands, with mix 43 having a slight advantage from 14 to 30 MHz). If your feedlines are 100 ft or less, loss will be less than 1dB on 40M and below, so an RG8X like LMR240, Belden 9258, or the Wireman&39;s CQ118 are a good choice. FOR USE IN SWINE FEED ONLY. 2 dB at 400 MHz & above at 100 feet. 5 dB, or 0. At marine VHF frequencies, it&x27;s loss is 4.

The coax cable is very high quality with 95 copper braid shield, and the signal retention is easily. That being said I personally would use something like RG-213, which is a more durable cable, and will have a bit less loss in the process. A 95 shielding rating prevents signal leak and outside interference, resulting in longer transmission range and a clearer signal. Ferrite is made in different formulas, called mixes. General Use RG400 is mostly used in Duplexers, Baluns. If you are &39;into&39; amateur radio. If you lube the coax slightly you can get 3 turns of RG8X through these. 5 out of 5 stars 7 Wrapping 33 feet of wire around a 20 foot pole takes a few minutes but you end up with a light weight antenna that can be leaned against. LMR-400 is arguably the most common LMR cable, being a replacement for RG8. The coax cable is very high quality with 95 copper braid shield, and the signal retention is easily. For VHFUHF you need less loss. Best Coax for Ham Radio Reviews. any Guy Wires or Ropes. Antenna was resonant on the bands but it did fine. 61 in the. RG-8 is fine for HF 1-54 MHz, but once you get above that then the loss is higher. The RG8X coax cable and UHF connectors both work perfectly well for HF. 005MHz to 14. Jim Heath W6LG shows what happened to RG8X that had 1500 applied. LMR240 is also an option, but remember the LMR cables have a solid center conductor and it will break if you swap radios often, LMRis very inflexible and will crack internally without warning if. Photo 2 Three Common Coax Types. A full-size Delta Loop, fed in the bottom corner, is a good low angle radiator and is great for working DX. VHF is another thing altogether.
