Hi Caarlo, Did you try to rotate it? For some stations my EFHW is better, for other Loop is better (on different bands - switching with A/B coax switch). But I'm still planning to put it on rotator to

Hi Sam, Thanks for the suggestion, but I need a more noticeable SNR increase than just a bit. Right now it is some 3-6dB behind my full sized antennas, and my initial goal was to outperform the SNR of

Hi Martin, I used a couple on each end. With a just a couple of these same snap-ons on the PC supply cable solved a problem with my WebSDR, as there were some very noticeable periodical strips along

Hi Martin and Caarlo, Did that for my LZ1AQ: 2 stacked FT240-31 with SFTP CAT-8 wrapped around. I think it helped a bit compared to just a snap one single (but thick)

Hi Martin, Thank you! That's great to know! Simon <martin_ehrenfried@...> wrote:

Ideally you need to model it to see for yourself what the pattern looks like, but the gain is within a few dB, until the elevation drops below about 15 degrees, then it falls off more rapidly. This

Hi Caarlo, Sorry for asking but have you tried cross-parallel loop configuration with two 1m loops? Maybe worth a try. I have commercial LZ1AQ, so I can quickly click relays and see the differences.

Hi Martin, Near the GND loop will become NVIS even for higher bands but I assume that shouldn't affect SNR (which we care about mostly) much until signal level becomes very low? Martin, how would you

Hi Caaarlo, How many ferrite snap-ons did you add ? With just one pass of the coax, you would probably need 20 or more, before you might notice any difference at HF frequencies. Several turns,

Ok, I guess I am losing the battle. Last night I tested a smaller loop (0.5m diameter) hoping that the lower pickup level will increase linearity and improve SNR. But SNR did not change. Pickup

Thanks Steve.

Sorry for the delay in replying to my thread. I went in for a routine follow up for my knee surgery and the surgeon is really concerned about the swelling of my right calf, so I had the joy of a non

When Wellbrook was in business I used to buy a new FLG100LN every year due to nearby lightning discharge zapping it. Now I make my own, using one of Everett's boards. My current one died last

If you are mounting it vertically, height doesn't matter too much, and I wouldn't bother going higher than about 2m AGL. The advantage of small antennas, is that you can often place then in

Copper to fibre convertors are cheap, and so is fibre. If you factor in the cost of the decent external copper Ethernet cable, and associated protective devices, fibre may work out to be less

?The best way to protect the loop amp is to use a relay to short out the antenna input when transmitting. Most transceivers have a key out that can be used to kill the power to the loop amp, which

Martin, From engineering prospective, having less headackes, by running a fiberoptics cable between two buildings with electro-optical convertors is the best solution. However, it might cause a

Hi Henry, Unfortunately I don't have info on these earlier versions such as your 1530L. Steve AA7U

Be aware, loop antennas that use Ethernet cable between the amplifier head unit and interface unit, may not be wired, or operating, in the same way that structured network cable does. As a result, it

Who told you that Polyphaser's SPD product with screw connections for each lead of Ethernet cable is the only solution in town? There are many other sources ( Citel, TUPAVCO etc. ) that do not use
