Jun 30, 2017 · In this video, I'm showing how I installed my PL-259 connector on a RG-213 (or RG-8) coaxial cable. I'm not the only one using this technic but after 25 years of hamming this is the best one. Please note that if you make a connector while the other end is connected to a DC Ground antenna, the PL-259 will be short when tested, that's normal.

Jun 30, 2017 · Testify! My 63-watt Hakko 456 works great for this. Ceramic heater and very large tip. Lots of latent heat for those big connectors.

Feb 19, 2004 · wind an RF Choke at the antenna end of the coax. Wind maybe 6-8 turns of RG-213 (or whatever you are using) about a foot below the dipole center insulator. If you make the 6-8 turns maybe 8-12 inches in diameter and tape it together then let it drop down. Leave an extra 3-4 feet of coax in your feed line and wind the coil. this is an RF CHoke.

Dec 23, 2016 · I was really wondering that same thing when I made my 1st mag loop using the shield portion of a piece RG-8 about 18 inches in length. When I made it into a loop it was roughly 7 inches in diameter. Then I cut another piece of RG-8 about 91 inches (5 times the inner loop) and connected the variable capacitor to each end using the shield portion.

Mar 15, 2018 · Even RG-8 size cables can suffer from a similar problem if the outer jacket material, shield and center insulator material just happen to be the wrong combination. Water penetration is a BIGGIE! I saw a 50 ft piece of LMR-400 turned into a big attenuator in about a month because the connector at the antenna end was not installed correctly and ...

Aug 31, 2017 · The wire used is #14 house wire for the 16-ft counterpoise and #14 copper clad iron wire for the 53-ft section. The 20-ft of feedline connected between the 1:1 Balun and the 9:1 UnUn is composed of an 18-ft RG-8X line which is connected to a 2-ft RG-58 pigtail coming out of the UnUn. The feedline to the shack is RG-8.

Sep 29, 2021 · RG-400, RG-142 and as was mentioned 303 all good for Balun building, or just get 14ga enamel magnet wire and do that. If I do use a straight dipole, I will build an UNUN common mode choke and put together a T-Match and let that be the transformer.

May 16, 2024 · I have a homebrew trap inverted V with the center at 40 feet and the ends at 12 feet on a small suburban lot. The traps are N4UU-style using 2 inch PVC pipe and RG-8 coax. According to LOTW, as of 9 May 2024, 59,716 QSOs, 139 DXCC entities (73 on 80, 125 on 40, 114 on 20), WAS on 40 and 20 and 48 states on 80. 100% CW using 100 homebrew watts.

Dec 8, 2020 · Using RG/U 58 cable, the K factor (length/diameter ratios) for the wire end is .97, and the K for the shielded end is .95 based on 1/2 wavelength of cable and the table in the ARRL Antenna Handbook. (You may need to convert from American Wire Gauge parameters to metric units to solve.) Now let's apply the K factor from the formula:
