B w vs300a manual

I would recommend this antenna as it fits in with my community. I wanted to update this review I made in further after using this antenna. Especially after doing modifications to it which has significantly improved the antennas performance. Other amateurs we have talked to have related that the signal penetration is superb and was wondering what type of power we are using.

When I relate that I am only running no more than watts it definitely sparks of conversation of how especially given the recent band conditions we have all experienced. I will be reviewing this on our website that we will be updating very soon and all details will be there. From meters probably in theory a full wave vertical. It does especially well on and 80 meters probably not a complete full wave but very close. We are still finishing out calculations at this time as this is a new antenna design.

Visit soon for details on how you can improve this antennas performance. We use no linear amplifier at all but in this configuration it will easily handle full power. Time Owned: more than 12 months. This ultra simple vertical antenna is the real deal! I bought one back in the 70's and used it as a Novice. After a 35 year absence from the air I decided to get my station back into operation.

Being the dead of a Wisconsin winter, installing antennas was a problem. I took this old 18 ft. With 2 ft. No radials or ground system of any kind. The antenna tunes perfectly on 80, 40, and 10 meters.

VSWR is a tad high on 15, and 20, but the performance far exceeds any expectations. With just 65 watts of power I've worked 40 DX countries, using 10, 15 and 20 meters. If I can hear them, I get them. Surrounded by oak and maple trees it's nearly invisible. I couldn't be happier. I had two of these antennas back in the 's. And again I bought the third one in The secondary reason was that it is not complicated to become QRV on the 10, 15, 20, 40 and 80 meter bands.

As has been pointed out, the 18VS cannot be used without radials or some other metal counterpoise. In my case with all three antennas I used the metal plates of the roof of my house which worked fine. The antenna works on 10, 15, 20, 40 and 80 meters. However, it needs to be realized that if you want to change bands, you will need to manually tap the loading coil at the base for each band.

Consequently, it makes life easier if access to the antenna is not difficult. I have never tried to resonate the antenna at the WARC bands 12, 17 and 30 meters , but I am sure that it is possible. The 18VS is a good antenna and it works well as any other vertical on the higher bands; even works OK on 40 meters. However, do not expect DX contacts on 80 meters. It is nevertheless fine for local contacts on that band.

The antenna is not strongly built and the hardware that comes with it could be of better quality. That is the main reason why I give it 4 out of 5. Terrible as intended. Don't even mess with it for 80 and 40 in my opinion. Those bands are a gimmick. Rip the coil off, put an L network or remote tuner at the base, and it'll tear up If you want to get really crafty, an L network with a 1. If you don't have a good ground plane, you're going to see terrible performance, especially on the lower bands.

Not bad for 80 bucks. You could build your own with an aluminum plate and four chunks of tube and two insulators, though. Mine lives on after two years of apartment hopping and six years on a 20 foot mast in my backyard set as a 20M monobander.

It's now bolted to the front of our 37 foot motorhome, and the full length chassis rails plus a coupe of fanned out radials keep it goin' all night long. Fed through an old Kenwood manual tuner and a 10 foot coax pigtail, no coil or matching at the base. Hope to hear you soon on it! This makes absolutely zero sense. The efficiency of a vertical without radials is severely compromised. I recently acquired this antenna from a total stranger who was not getting out of amateur radio.

Meet him at a gas station in Montana after he noticed the screwdriver antenna on my vehicle. The quality of the antenna is what you would expect for a "budget" HF vertical. I would certainly not trust the base coil or it's clip lead over long term exposure out in the elements though. SWR was decent on these 8 bands. Next step was to give the antenna the "QRO challenge".

According to it's manual it's rated for 1. OK, let's try that out. Held up just fine without any changes in SWR or the coil arcing. I then attached a length of 20 AWG wire a few feet down from the tip of the vertical. Using the analyzer I wanted to see if the antenna would be of any use on meters.

A poor mans inverted L if you will. The coil would probably get worse in salt air environments. Worked all 9 HF bands - 10 meters as described above with fair results. It's likely one could also work 60 meters with the aid of a tuner bringing this to a 10 band HF vertical Tom KC0W.

I had intended to wait until I'd had more time to see what it can do before posting my review, but after reading these again over dinner tonight, I have a few things I'd like to say before I forget. First off, there are several reviews here from users who have been disappointed, but from what I have experienced so far and from what I have read, all but one of these negatives is due to one of two things.

Either you've assembled the antenna wrong, or you're not using it correctly. Please bear with me, I am not criticizing, I am trying to be like nearly all other hams I have ever met - helpful in some way. Good luck to the repair!
