Personally, I think it would be slick to do a dual axis rotor system with a yagi for radio astronomy. |

Personally, I think it would be slick to do a dual axis rotor system with a yagi for radio astronomy. I'd say that if you're chasing MW DX the rotor is an absolute 'must have'; but I wouldn't say this where SW DX is concerned. I was sort of hoping that the antenna would have directional characteristics above, say, 4500 khz; but it sure doesn't seem to, at least in my location and listening conditions. I guess I'll just have to resign myself to an excellent omnidirectional antenna... ![]() Steve |

My review of the wellbrook ALA 330S loop antenna so far.
first things first i was going to test this antenna mounted in my loft but the loop would not fit through the loft door opening. So my first test was carried out as follows. i stood the antenna in the middle of my room floor. i had the 330S connected to an antenna switch so i could flick the switch to compare the performance between other antennas i have mounted out doors.. when i had the 330S connected up like this just sitting in the middle of my room floor. my other antennas did perform better signal wise but the wellbrook was much quieter but the signals were a lot lower.....one thing i did notice is that why i was useing the wellbrook 330S in this position is i tuned into a distant signal that i could hear why using the 330S then i flicked the antenna switch between my two other out door antennas and i could only hear the signal using the 330S as the noise was a lot less.... this is as far as i have progressed so far..... my next test will be to locate the antenna on a fence post in my back garden.. then when i get time i will be mounting it about 50+ feet high... as for my circumstances my farther in laws cancer treatment well. he was admitted to Hospital on Monday 24th and was expecting to have his operation first thing Tuesday. his operation was going to take 12+ hours .. well on the Tuesday the doctors got my farther in-law all ready for his operation they went as far as wheeling him down to the operating room they had injected him with strong pain killers and relaxants then just as they were to wheel him into the operating room the operation was cancelled due to the intensive care bed had been taken and he was sent home later that day and he now has to wait for another couple of weeks for his operation and it could be cancelled again. how ****ing cruel is that this country is going to the wall the health service is totally ****. one day i am going to get out of this god forbidden country...... As soon as i have time i will test the Wellbrook 330S mounted out doors..... all in all the antenna seemed to perform better than my out door antennas but the signal was low but then again it was only sitting on the floor.... John "Joe Analssandrini" wrote in message ps.com... Hello Again John "Big Boy," By now (January 25) you may have tried your new antenna. Any comments? (I hope your family member is recovering well and I know everyone on this group is wishing you and yours well.) Best, Joe big boy now wrote: A week ago i placed my order for a Wellbrook ALA330S active antenna loop... Well the ALA330S arrived today i will be testing the antenna indoors tomorrow. i will add updates on the performance of the ALA-330S antenna as soon as i can as my spare time is tight as i am in and out visiting a family member in hospital after cancer treatment...... |

A lady whom is fifty years old,she and her dad and her husband are
originaly from Ireland.I met them via the internet a little over five years ago,they live in Bognor Regis,West Sussex,England about sixty something miles south of London.About two years ago her dad went to Ireland (Caherconlish,near Limerick) to visit friends.His doctor in Bognor Regis had told him it was ok to make the trip to Ireland,he had been having prostate gland problems.Almost as soon as he got to Ireland,he was in very severe pain.He wound up at Dooradoyle Hospital,Limerick,his prostate gland was just about to burst.If he haden't made that trip to Ireland,chances are he would have died in Bognor Regis. cuhulin |

![]() Steve (or anyone else), how do you like your Welbrook loop, and where do I buy one? My main interest is in putting it up about 30' feet and rotating it to null out local electrical QRN. How does it perform in this regard? Leonard -- "Everything that rises must converge" --Flannery O'Connor I think the ALA-330S is a wonderful antenna. It didn't work well for me indoors due to noise, but now that it's mounted outdoors it's doing extremely well. If you want to purchase one, you can contact the Shortwave Shop and order one with a credit card. Visit their website for contact information: http://www.shortwave.co.uk Steve |

Dear John,
Compared to what you, your father-in-law, and your family are going through, questions about the Wellbrook antenna seem insignficant. I hope you and yours find the strength to pull through this. (The "dedicated" health-care "professionals" in ALL countries offer poor care nowadays. It seems to me [in the USA] that the only "dedication" many [most?] of these people seem to have is to themselves.) So I'll just make one quick comment; you will be able to observe this for yourself (and, actually, you already have). Many antennas will cause the S-meter to show a stronger signal than the Wellbrook, yet, especially in the summer, you will be able to hear the signal far better via the Wellbrook than most other antennas. This is because the other antennas boost the noise along with the signal. The Wellbrook attenuates electrical and atmospheric noise. Its gain is not as great as many other antennas, but its signal-to-noise ratio (which is all in which you are interested) is far better than any other antenna I have personally tried or experienced. In short, it just doesn't matter what the S-meter reads. The bottom line is: "can you hear the signal with good intelligibility?" I (and I know all the rest of the members of this group) sincerely wish your father-in-law a speedy and complete recovery and for you and your family to get through this most terrible time. Best, Joe |
