Reviewing The RadioWavz DX (OCF) Windom Antenna. It's an Off Center Fed Dipole Antenna that exhibits outstanding performance on multiple bands, typically without a tuner. Let's take a look!

With an 80 meter OCFD you have to have 80 meters resonate low in the band in order to get 40, 20, 10 meters to line up right. If you shorten it, cut the same proportion from each side. I usually shoot for 80 m to be at 3.55 - 3.58 mhz. OCFD's are usually divided about 1/3 - 2/3 (though I've had good results with a 29.5% feedpoint), so if you are going to take off 12", take 4" from the short side, and 8" from the long side. Don't just try to tune one band. See what the effects are on all usable bands. Some guys have added another pair of legs, like a fan dipole, only it would be a fan OCFD, in order to gain 30 and 15 meters. Still, that is a lot of bands for the amount of wire in the air. A 66' or 40m OCFD will work 40, 20, and 10 meters, and is an excellent Field Day, Emergency, Portable antenna. I talked to Japan from Louisiana with a 40m OCFD hung between trees at festival. I LIKE OCFD's and have built a number of them for clubs and new hams, all with the same good results as you have. Balun must be a current balun, not voltage. Don't try to get it perfect, that's what you have a tuner for. Get on the air, have fun!

I've been using a Radio Wavz G5RV Jr. for a couple of years. Those ends are great, strong and easy to adjust.

@MikeN2MAK Год назад

The SWR readings made me realize how much I really need to graduate from the NanoVNA to a RigExpert.

@robincross4625 Год назад

In the picture your antenna is parallel with the power lines, or so it appears. That makes a nice transformer, w0fen

@boydsharp Год назад

I use this exact antenna and it has performed flawlessly.

@benjaminhughdavis Год назад

Im amazed how much i like my Radiowavz OCF. Its totally replaced my 40/20/10m parrallel dipole.

@Aloysius-73 Год назад

I have the 80 short OCFD and love it. I get great reports. And they have great customer service.

@jameyevans29 Год назад

The only band mine was resonate on was 40 meters. But I am happy with the performance

@stevegordon2869 5 дней назад

I run a 240-31 core about 4 ft below 4:1 balun 6 to 10 turns of coax on core helps alot with noise.

@jimlynch9390 Год назад

I have an 80-10 Carolina Windom which is a similar antenna, that I had up at the same time as a W9INN multi band antenna at the same height. The Windom had a lower noise floor and signals were from a half s-unit to a full s-unit better. They were roughly parallel and probably 75' apart. I'm extremely happy with the Windom and have used it for quite a few years now. At least 15. I use it with a LDG tuner on all hf bands. It's about 35' in the air.

@thuff3207 Год назад

I have one and it works well with one issue. A squirrel ate about 10ft off of it so keep the squirrels away and you will have a nice antenna. Now I wonder if a diversity receiver would help reduce your noise to have a lower noise floor.

@mikemcdonald5147 3 месяца назад

are u sure your name is mike i thought my name was mike LOL :) good explanation of the antenna love me some radio wavz.

@Blake-W8LB 9 месяцев назад

I finally installed mine today, all of my SWR readings were slightly lower than yours except 20m. I’m 2.3 at 14.14.

@HamRadioWithKE0MAD Год назад

Emmett really believes in his products and stands behind them to back it up.

@Blake-W8LB Год назад

Will you make a video trimming it when you do? Also which tuner would you reccomend for a base station running 100w FT8? I have an LDG 100 but it says its only rated for 25w digital.

@sciencefollower Год назад

VERY MUCH APPRECIATED. AP2KD.

@patriot9455 Год назад

I have a transformer at either end of my property and will be running about 15 to 20 feet from my 110/220 line into the house. I can feel your pain. I wonder if a QRP signal can make it out of or into the mess.

@bassmanjr100 6 месяцев назад

My HWEF does, 40, 20, 10 no tuner. It does 12, 15, and 17 with an internal tuner.

@kd5you1 6 месяцев назад

I just purchased the DP84 and it seems to be well built. I was a little confused as to why there were no specs on the antenna other than it is designed for 40 and 80 meters, and it handles 1500 watts. 73 KD5YOU

@kr4awkr4aw5 2 месяца назад

do these antennas have balums? Im using the parts of one OCF Windom.

@charlesrader3845 11 месяцев назад

I had one of their DX160 OCF in the air for 8 years. Only had to replace the rope every 2 years. No issues until this year and the wire broke into. So, obviously I purchased another Radiowavz. Actually ordered the DX160 Pro Line this time. Put it up in exactly the same spot the short leg broke that night. Pulled off the long leg off the OLD DX160 and replaced the short leg on the new one and got it back in the air. The next morning the long leg snapped. These are clean cuts like the wire was already nicked in that spot. Kinda scared to order another one from them. Because that was a lot of money. First one was amazing but the upgraded Pro LIne lasted less then 12 hours.

@saxmusicmail Месяц назад

Don't try to pull it quit so tight. You'll never get all the droop out, and a little droop won't hurt anything. Support the balun... and weight of the coax. The whole thing can be a lop-sided inverted V with no problem, but the balun and coax is heavy.

@Trent28888 Год назад

Good to see it works,pity they dont sell a portable version😐

@david_W5QDF Год назад

Wonder if they make an EFHW & how it works.

@mrppassman Год назад

What is the total length of the antenna? Did you need to shorten it at all?

@nfsusna 8 месяцев назад

Did you tune out your coax run? Or is your metering reading the coax plus antenna?

@off-trailseeking3965 Год назад

Type TFFN/MTW 16 gauge ......machine tool wire. Literally pulled 10s/1000ft of this wire as an electrician for 45 years. Great wire and should weather outside decent for years. Will not stretch much either.

@chrisnmichelle0218 Год назад

Would have been better being THHN, the common electrical wire I pulled for years, quick look up on TFFN states "Like THHN/ THWN, TFFN is immune to oil and gas; however, it does not really perform well when it comes to water and moisture exposure." Great in conduit, but not made for weather... seems like an oops

Hey another michigander! Hello from EN73 K8OTY

@jameyevans29 Год назад

Mine RADIOWAVZ DX80 came with 14 gauge wire. #14 mtw

@allenpamscofield 10 месяцев назад

Mine as well.

@Chris_KI4WCO Год назад

Couldn't you take an 8ft piece of PVC to give it strain relief in the middle and just zip tie it to the antenna?

@GH0ST369 Год назад

See this is why manufacturers need to incorporate kevlar into the shielding, it dramatically reduces the stretch of antenna wires. Hams will gladly pay the extra cost, at least make it a test market option...

@Davidjb37721 Год назад

Tighten the wires on your meter box on your breaker box

@BusDriverRFI Год назад

My antenna wires aren't far from my antenna wires. They never are. They're always just right there.

@hamradiotube Год назад

Ahh I see you caught my mistake in speaking. Words are only my second language lol.

@BusDriverRFI Год назад

@@hamradiotube I'm an RFI school bus driver. There's not much I don't catch.

@pale_2111 Год назад

It's a shame it doesn't do 15m because that's my favorite band to work.

@wrinkyscarnagecrew Год назад

Upgraded g5rv?

@Blake-W8LB Год назад

Not really this is an off center fed dipole with a matching transformer G5RV is center-fed and uses ladder line as an impedance match, more along the lines of a double zepp.
