The Daily Antenna: What type of wire?

05/07/2019· What type of wire should you use in your antennas? Insulated or bare. Enamel-covered or plastic? Single or multi-conductor? Then there''s material.

Flexible vs. Semi Rigid vs. Rigid RF (Coax) Cable

13/01/2012· Semi-rigid designs provide better dielectric properties and shielding quality. Probably the most important difference between flexible and semi-rigid coaxial cable is that the braided outer or film shield is replaced with a solid metal outer sheath which has is bendable but flexible. Once formed (bent) the cable’s configuration is fixed.

Zenith Model 7S634R 7-S-634R Restoration

Some rubber covered wire was bad - the insulation would crule and fall off if the wire was moved even a slight amount. Any bad wiring would have to be replaced, including the wiring to the tone control panel. Three resistors had drifted and were now out of tolerance. Strangely, all were 47K 1/2 watt carbon composition types!

Dipole-bare or insulated wire | QRZ Forums

19/11/2003· It is readily available - and insulation color can help camouflage or make the wire more visible - depending upon your situation. The red insulation does fade under sunlight (UV). The copper will stretch a bit - under tension - and some will suggest CopperWeld (copper plated over steel wire) - for installations where the wire is under tension.

LMR-100 vs RG316 | Product Knockout | Wire …

26/04/2017· LMR-100 has a conductor that is solid bare copper clad steel, where RG316 has a stranded silver covered copper clad steel conductor. RG-316 having a stranded conductor, makes it more flexible than the solid conductor of LMR-100. Another major difference one can see from the chart is that RG316 has a higher temperature rating.

Loop Antenna Dimensions - pagesperso-orange.fr

If you use bare wire, common sense dictates that you use good quality insulators as "stand offs" to prevent adjacent materials from overheating. (Very large currents can circulate in loop antennas, and wires can get quite warm!) So generally for the HF bands, stranded wire, covered or bare, is a good choice. At VHF, you may use solid wire. This

Build the Slim JIM Antenna

2. Draw tension the bare wire by mounting one end of the wire in a vise or post, then with a plier at the other end, pull the wire tout several times (2-3 jerks will do) until it is straight with no kinks. 3. Layout the wire in a flat surface or on the floor and follow the illustration in Fig. 4 to make the

coated wire vers. bare copper wire ka4dsk | QRZ Forums

29/04/2014· It is a good question, when DIY Building a wire antenna. The Wave Equation is mathematical relationship between the speed (v) of a wave and its wavelength (λ) and frequency (f). Using the syols v, λ, and f, the equation can be rewritten as: v = λ * f or λ = v / f === As you remeer, the Speed of Light, c is 299,792,458 meters per second,

What Is the Difference Between Wire & Cable in …

A wire consists of a single strand or a group of strands of an electrically conductive material (conductor). This material is normally composed of aluminum or copper. Wires can come bare, or covered in a protective or color-coded sheath.

Insulated vs. Bare Ground Wire Appliion | Mike …

15/06/2018· Jun 8, 2018. #1. Hey All, I may be overthinking this one, but one of our interns asked about the appliion of bare ground wire vs insulated ground wire, and I can''t stop second-guessing my answer. My gut response was that bare copper wire allows the user to connect to earth or other grid materials (thinking ground grids, rebar and the like

Solid bare wire vs insulated wire elements? Thick …

I have heard that using coated wire will affect the antenna some way, but I use bare 16ga stranded copper wire for my dipoles and such. For weatherproofing, copper does rust, and so you can paint it or cover it, but be sure not to use EMT (grey plastic) as I have heard it contains metal to reduce EMI/RFI from the wires contained within.

How to Identify Positive and Negative Wires: 10 …

08/02/2021· Identify the black positive wire on a ceiling light fixture. When you''re hanging a chandelier or any other ceiling light, first find the 3 wires coming out of the hole in the ceiling where the light will go. Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire …

Is copper-clad steel a good material for wire …

Copper clad steel is a good antenna wire. It''s not the best for every appliion, but it''s good for most appliions. Keep in mind that at frequencies between 3.5MHz and 30MHz the conductor''s skin depth, the depth at which 63% of the electrical current flows, is between 35uM and 12uM for copper wire. The link you gave has 30% or more copper

Understanding Shielded Cable - Mouser

Usually, rather than attempting to ground the entire shield, the drain wire is used to terminate and ground the shield. A braid is a woven mesh of bare or tinned copper wires. The braid provides a low-resistance path to ground and is much easier to termination by crimping or soldering when attaching a connector.

Wire Antennas for the Beginner - ARRL

install an antenna where it can contact a public utility wire. You may have a pair of 70-foot trees perfectly positioned to sup- port a wire beam aimed at your favorite DX area. But if a power line runs between the trees, forget it. If you have plenty of room for a real antenna "farm," then a separate antenna and feed line for each band is the

Antenna Calculator - Ham Radio Secrets

05/06/2021· The antenna calculator above will give you a wire length for the inverted ''V'' which will be about 4% shorter than that of a dipole at the same desired frequency of operation. This will give you some leeway to trim the wire ends back if the inverted V resonates too low for your purpose when installed in its final position.

Cheap Yagis for 2450 MHz

Bare Wire vs. Insulated Wire Making that quad antenna designed for bare #12 copper wire out of insulated #12 copper wire moved it down in frequency about 5%, didn''t it? Your 147-MHz quad resonates in the 130s, and the element spac- ing now is all wrong. …

Antenna Wire: Stainless Steel vs. Copper – VK2: …

23/06/2011· However, it would be OK for an antenna with a higher RF impedance than a single dipole (e.g. 300 ohm or greater antenna, (e.g. folded dipole etc.)) asthe higher RF impedance would act to swamp out the affects of the RF impedance of the stainless. The “best” wire to use for a wire antenna must have the (conflicting) properties of:

G0KYA''s HF End Fed Half Wave (EFHW) antenna – construction

Bare the wires at one end of the coax and leave the other end as it is – you will be snipping this with cutters to tune the antenna later. Band Starting coax capacitor length (you will cut approx. 1-2in shorter than this to tune) Length of half wave antenna (assuming insulated wire) 20m (14.175MHz) 35.5cm (14in) 10.05m (32ft 11.6in)

25/12/2010· But a bunch of wire in the air, connected via an antenna coupler will also work “multiband” just as well from the perspective of the guy on the “receiving” end. “The G5RV antenna system is suitable for multi-band operation, just as any wire from about 88 to 140 feet might be.” Antenna design expert L.B. Cebik (Reference 89).

Antenna Wires – Which Is Better? © Bjarne Mjelde www

Ever since I began to erect "proper" antennas, I have used insulated copper wire, usually 1.5 mm2 (somewhere between AWG14 and AWG15). Not because 1.5 mm2 was necessarily perfect for the job, but because it made a good compromise between strength, weight and price. Smaller wires (such as 0.75 mm2) tend to break easily, while thicker wires (such as 2.5 mm2) are heavy and need more …
