What coax should be used for HF, VHF, or UHF frequencies? We recommend looking at the Coaxial Cable Loss Chart to determine what coax to use. 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. While VHF and UHF benefit more from RG-213 (RG213) or heavier coax

Larger and lower loss than RG-58 but still convenient for shorter cable runs and jumpers, Up to 50 feet in length at 50 MHz or below (Rule of Thumb) Up to 25 feet in length at 146 MHz (Rule of Thumb) RG-8U. (LMR-400) 0.405 inch. General purpose coaxial cable, best for long cable runs. Comparison of three commonly used types of coaxial cable.

I also use LMR 400 for outdoor runs from the house to the antenna, but use skinnier, more flexible coax from the antenna switch to the rig. Here is a nice coax loss calculator. RG-8/U Foam. The losses aren't much more than LMR-400, it's cheaper, and the foam dielectric is so much more flexible and easier to deal with.

2. MPD Digital LMR-400-PL259-UHF-18inch Coax Cable. A popular option for critical communications, such as in the police and army, this HF coax cable is another option you should not miss. The cable uses a proprietary dielectric material, which is responsible for its low loss.

The three most commonly used coax types that are available in marine stores that meet these specifications are RG-58U, RG-8X, and RG-213 (which replaced the older RG-8U). Which one you choose is a trade-off between the amount of signal loss in the cable, the cost and the wire size. Photo 2: Three Common Coax Types.

Feedline loss is measured in decibels (Db) per 100 feet. The decibel scale is logarithmic, so a loss of 3 Db is a 50% reduction in power. A 6db loss is 50% on top of 50%, and so on. For example, if you have 6 db of feedline loss, your 50 watt signal coming out of the radio will be 12.5 watts as it enters the feedpoint of the antenna.

Signal loss is also important and it varies with the length of the cable and with the frequency. At the 3- 30 MHz HF frequencies the signal loss for most coax is minimal. The loss increases when you get to UHF and VHF. A 50 ft length of RG 58 at HF is acceptable for most people, but the loss is higher at UHF frequencies.

Still, for most VHF/UHF FM operations this capacity is much more than adequate. Consider the coaxial cable routing for your potential antenna locations and identify the best combination of cable type for location, routing, and loss.

You'll most likely find that on the HF frequencies, the coax loss for the various types of coax is pretty close (unlike on the VHF and UHF bands, where it will vary quite a bit). Your coax choice on HF won't really affect your signal all that much (the difference between RG-58 and LMR-900 for a 200' run would be huge on the higher frequencies

In HF applications, the impedance mismatch can be further reduced by the use of an antenna tuner. The tuner gives the transmitter the 50 Ohm match that it expects. So for their HF antenna systems, many hams will use RG-59 or RG-6 because it's cheaper than 50 Ohm RG-58 or RG-8, and any mismatch can be resolved by the tuner.

So I recently picked up one of the N9TAX Dual band Slim-jims to try to reach farther with my Baofeng AR-152 when I'm at home. Currently it's just hung up next to my window, linked to the radio with an SO-239 to BNC adapter, about 3 feet of RG-58C/U BNC cable, and a BNC to SMA adapter on the radio itself. I'm hoping to install it in the attic to

Here's one you could homebrew, using a diode matrix, push button switches magnetic latch relays and SO-239s. The schematic shown is for 3 antennas but it's extendable. Freewheeling diodes for the relay coils and LED indicators are not shown. The SO-239 bodies are to be mounted on the aluminium enclosure, interconnected and earthed.

The radio I'll be using is a 25W mobile base. The only Coax I could find at the moment is RG-58 although I was recommended some LMR400. I'll probably be outsourcing some tomorrow due to not having any other clue as to where to get it where I live (Seattle. No radio retailers in this area.) TL;DR What Coax would you recommend for VHF/UHF?

With your scanner the RG-6 will work well. For RX TX on VHF the RG-6 will work but it is not the best solution for all around use. In most cases you will get better service with 50 ohm designed for radio use. If size is an issue go with an Alpha, Commscope or Coleman RG-8x or Times 240. The 240 has extremely low loss at VHF freqs.
