They both have since been moved along to new homes.I have a 43 foot vertical monopole antenna. Originally I matched it to the transceiver with a substantial matchbox/antenna tuner located in the shack. The conventional wisdom is one can more effectively and efficiently match these big sticks at the feed point with a remotely located matchbox/antenna tuner. To this end,The MFJ 2990 is a 43 foot vertical antena that is very easy to put up and it is well built But the problem is that this antenna will not tune on 160 meters, I have 26 radials and I had to build and install a huge coil that sits one foot above the balum and adjust it with the antenna analyzer so I could tune 80 meters.It shows field strength measurements I made some time ago, which compare a 30ft vertical fed with an auto-tuner at the base vs. the same antenna fed a 4:1 balun wound with 75 ohm coax on two separate type 43 ferrite cores and a remotely sited tuner fed via 200ft of low loss LDF2-50 coax vs. a broadband antenna of the same element length.The MFJ-2990 is a 43-foot self-supporting vertical antenna that covers 160-6 meters with the use of an wide range antenna tuner. Because the top 9-foot section of the antenna consists of a 1/8" diameter stainless steel whip, the MFJ-2990 has the lowest wind-loading and has the least visual impact of any 43-foot vertical antenna on the market.By TF3XO.

When installing ground-mounted radials use radial lengths between 20 and 43 feet, with 43 foot being the choice for best performance. If you have to use shorter length radials, put more down. A good place to start is a minimum of 32 with 120 being the best.I first considered a non-resonant 43 foot vertical which seems to have been all the rage over the past decade or so among hams. However as the 43 foot vertical is non resonant on any band, it would require the use of a tuner. Most of the articles I read agreed that the optimum location of the tuner is at the base of the antenna.From: [email protected] [mailto:[email protected]] On Behalf Of Nolan - KI5IO Sent: Monday, July 9, 2018 2:44 PM To: [email protected] Subject: [butternut] HF9V vs. 43' Vertical experience??

DXing on 40 meters im-This HyGain AV-6160 is a 43-foot selfsupporting vertical antenna that covers 160 through 6 Meters with the use of an antenna tuner. It weighs just 20 lbs. and has a wind load of just 2 square feet. The antenna diameter is 2in OD at the bottom, 0.120" thick-walled tubing. It is nine sections including the stainless steeA 43 ft vertical mounted as a Horizontal Antenna is just that a 43 ft Horizontal Antenna Heavy duty 5kW, 4:1 unun designed for use with wire verticals, long wires and multiband monopole verticals. Utilizes stacked cores to deliver efficient broadband performance and high power rating across all HF frequencies.May 03, 2022 · Zero-Five 43 Foot Multi-Band Vertical Antenna. If you are looking for a contest winning, DX powerhouse antenna, this is not the antenna for you! If you live on a city lot or in a covenant restricted neighborhood, this could get you on the air on 160 through 10 meters. This antenna requires a good ground plane beneath it and I would suggest getting one of the radial plates from someone like DX Engineering. S9v 43 Foot Multiband Vertical - IT ONLY GETS BETTER!!! I reviewed this antenna in July and I still love, love, love it! This antenna continues to perform and surprise me. I've operated with 8 ground radials for quite a while and I could do a great job of busting through to Europe and the Carribean.A 43' vertical of heavy duty construction for use on 5 bands between 60m and 17m If you are finished with toys and would like a decent, high quality vertical built to last, you have come to the right place!

Make the antenna resonant - Unfortunately this is a narrow -band process. - Requires lot of antenna elements or traps to cover many HF bands. 2. Place a variable antenna tuner right at the antenna:My gut analysis says that a 43-foot vertical with 16 60-foot radials should be at least as effective on 160 meters as the HF9V was on 80 -- and possible somewhat better as the radial system is a huge component of performance and the radials would be twice as long (for the wavelength) as the HF9V radials were.My first setup was the way ZEROFIVE recommends installing the 43 vertical using a full range tuner and using a UNUN and a coil on the 43' vertical antenna this worked well up to 200 watts at my location, but after 200 watts the efficiency dropped. the present setup uses a screwdriver antenna in series with the 43' stinger and 3500' of radiales ...We carry the entire line of LDG vertical antennas.
