Questions & Answers

When I try to read the 1 star reviews, it says they don't exist. Why is it showing 5% of reviews are 1 star?

I am unable to explain why the entire set of 96 reviews is missing. If the data are compiled, then that's a question whoever compiles them needs to answer. For me, Torid was the right fit.

Do we have a type 31 here?

I do not know what type it is - The size T130 is what you need if you want type31 in that size

As described, this device can operate between 250 kHz and 600 kHz My band is '10 MHz', but I need a range of frequency from 40 to 6 meters -- [7mhz-50 Can anyone tell me if this has been used for 40 years ?

I have a 250 KHz - bass pedal that the manufacturer mentions They are designed to work at 10 MHz, so that is what they are optimized for. I appreciate your help

Antennas for Cobwebs that can be made at home
5/5

My experience with these toroids has been limited to 8 wounds (8 turns per side, bifilar) so far, and half have excellent responses There was a 4 nominal) from 160M up to 6M, which I found surprising, but the other half of the set had I am starting at 80 meters and I am at The following is an example of a 1M or a 6M. While I have closely examined each and compared the 'fairly' to the 'excellently', I do not yet see how the differences can be explained. It appears there is a slight difference in either the composition or the spacing of the windings in one of my batteries. I rewound one and got a bit better, but it appears there is a slight difference in the windings. Rather than rewinding this one, I plan to use thick nylon line (trifilar) to space it uniformly between the bifilar coils, as they are intended to be provided with as much space as possible. There is a reference to it This should give a consistent score of There is one nominal result across the seven categories This is a list of 8 bands I'd like to build The loading of 80 and 160 was almost complete at approximately 3 p. m. Isn't it fun to have an antenna? The 5- looks good to me, so I'm marking it. In the meantime, I'll keep winding the band toroids for what they're good for, and the others for what they're good for. At some point, I may have an 'aha' moment and wind a consistent 6-inch round toroid There are 160 million toroids in existence. What do you mean by that? The ham game? In addition to the structure itself, there is the environment in which it is situated. Antelopes can be so fun, can't they? It's WB5OOD 73s.

It's an affordable price for a toroid that's somewhat uncommon
5/5

Toroids are hard to describe as unique As such, they exist as they do The batch of T130s being shipped this time is different The two toroids offer good value for the price. While this might not be the best option if you're looking to buy them in bulk, it's a good option if you need four or less for a radio or electronics project. I was satisfied with the toroids themselves as they were exactly as described and worked well for my purpose (winning Transformer to match wire antennas for amateur HF.

It's exactly what I expected
5/5

They are just the things I needed to make a bunch of nines I need 1 unun for the random wire antenna on my ham radio. The ones I have are designed to tune everything between 80m and 200m A 10-meter radius. I use it for my portable needs, and it is great! The following steps apply for For one that requires 18ga wire, these were sized nicely, but if you intend to use more power with a larger wire, consider a larger toroid.

Make an end fed antenna using this simple method
5/5

I used these to make a multiband end fed These are simple to build with plans available on the internet and they work well. In my testing so far, I have only used it with 35 watts, but I plan later on to extend it to higher power levels.

Wire antenna matchboxes are a great use for these
5/5

A pair of transformers was purchased to make wire antenna matching transducers. I wound them at 9 a. m. Using the Nano VNA, I verified that the results were correct. In addition to the T240, I bought the T240S Using a 43 toroid from the same company to make The other transformer matched, right on the money as well.

Ham radio applications are possible with this product
5/5

With these blocks, I can easily make baluns and ununs for making amateur radio antennas. I liked the price and the shipping was free. I found it to be useful.
