So far received 47 votes for a total score of 6.78/10 – Sloping dipoles (some of the length is vertical) – Inverted Vee (some of the length vertical) • Top-loaded verticals – Inverted L – Inverted Tee • End-fed wires How About A Vertical? • A “good” vertical can beat a low dipole • Low means less than about 0.3λ – 40 ft on 40M – 80 ft on 80M – 160 ft on 160M • “Good” means efficient Some 43-foot antenna vendors claim the antenna can be matched from 160-10 meters with your in-shack tuner. One vendor says to use 150 feet of RG-213 for best all-band operation of the 43-foot antenna (so you can tune from the tuner in your shack). Another vendor says to ADD 150 feet of RG-213 to your cable run. ROHN H50 Foot Telescoping TV Antenna Mast. Made in the USA!

Nov 28, 2011 · Any vertical without ground radials is only half an antenna. I have tried the Cushcraft R7, it worked, but so did my 1/4 wl 40 meter vert with ground radials, the 1/4 wl with ground radials hands down much better than the cushcraft. Get 160-6 Meters Coverage and 1500 Watt Operation with a single antenna! This MFJ-2990 is a 43-foot self-supporting vertical antenna that covers 160 through 6 Meters with the use of an antenna tuner.

2008 honda goldwing blue book valueA 33.5 foot vertical will have a perfect 1:1 SWR on 15 meters with a resonance of close to 1:1 around 21.250 mHz. It becomes a 3/2 wave length antenna, which means it will have a much lower angle of radiation, approximately 18 degrees, and it will have about 3 dB of gain on 15 meters. Looking for feedback on a couple of different options for a stealth wire antenna at my apartment building. I have heard good things about vertical dipoles, but I don't personally know anyone who's used one. On the other hand, a straightforward base-tuned wire vertical seems like a solid choice.

a 33 foot vertical. If you have it lying around you could use it, but the extra weight really isn't worth it. Same for reinforcing by thickening the tubing on the inside. A hollow tube 2" in diameter with 0.058" walls is about 3 times stiffer than a SOLID 1" rod. Now, strength and stiffness are two different things, but you're better The antenna is comprised of three lengths of 12 foot aluminum which telescope together. The aluminum was purchased from the Yard Store in Wichita, KS, just 30 miles south of me. The Yard Store has a lot of surplus aircraft aluminum from Boeing, Spirit, Hawker/Beach, Cessna, and Bombardier.

10m (33 ft.) is OK for this antenna. It works for both 40 and 80m. The length is not critical, as long as it is at least 1/8 wavelength long on the lowest band. If you put down 10 radials this length, you will have a good working vertical on both bands. If time and circumstances permit, of course it is better to use a few more. Interfacing the antenna The 43 foot vertical is NOT resonant on any of the HF ham bands. The AD5X matching network with switched coils and 4:1 unun brings the SWR into a range accessible by Get 160-6 Meters Coverage and 1500 Watt Operation with a single antenna!

May 28, 2016 · Patterns of 43 foot Vertical Antenna on the major HF Bands. The peak radiation angles and relative antenna gain for each bands are: ~ 5 dBi @ 57° for 10 meters – impressive, but high angle. ~ 4 dbi @ 37° for 15 meters. ~ 1 dBi @ 16° for 20 meters – nice low angle. ~ 0 dBi @ 25° for 40 meters. All Bands Vertical Antenna-HF (homebrew) A few months ago my friend 9W2 AYR(Anuar) and I visited my new friend 9M2LR (Mr.Richard Lau) at Nibong Tebal, South of Seberang Perai, Penang. After a few talked he gave us an article about vertical antenna that he took from the internet.

Radiation Resistance = Power radiated / input current squared The other portions are ground loss and antenna structure loss that dissipate power as heat. Example: 160 m 50 ft vertical = 34.6 deg = 6 Ohms Rrad Feedpoint Radiation Resistance vs Degrees (Double for Dipole)

It extends to a whopping 33 feet -- a full quarter wave on 40 meters! The bottom section is 1 3/4 inches in diameter. It's great for portable and temporary use -- traveling, camping, from hotels, hamfests, field day, DX-peditions. Put up a full size inverted Vee dipole or full size vertical antenna in minutes and get full size performance!

Mar 04, 2018 · Figure 1 – The angle of radiation. This figure shows a vertical antenna, but the concept is the same for all types of antennas. The shaded area shows the most useful angles (10 – 20 degrees). To get this angle of radiation you will need to have your antenna from about 70 ft – 25 ft, respectively. end-hat added to my 2.5 m (8 ft) base loaded vertical In June of 2010, I decided to add an end-loading "hat" to my 2.5 m (8 ft) base-loaded vertical , and see what happens. That antenna has a fine-tuning bolt that is screwed into the threaded tip of the radiator. Dipole Antenna Calculator. The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Place a 1:1 Balun on the Antenna end of the Feedline. The antenna can be adjusted from 31,3ft (9,55m) to almost 35,7ft (10,90m) The usual total length of the antenna is 33 ft (10,03m). Top quality STAUFF (made in Germany) insulating Polyamide clamps are used for robust & secure mounting of the antenna on the thick (5mm) aluminium plate. The first antenna everybody probably makes is a dipole and the second a quarter wave vertical. The third antenna will probably be a multiband version of these antennas (or yagi). This is the third antenna.. Below a small description of an easy to make and cheap multiband wire vertical.
