Any thoughts on choosing between the Arrow and RDFAntennas for the MK 4? I did do some searching, but didn't find a direct comparison.

The Arrow is enough cheaper to help my budget and if you get the split boom version, it should be smaller for storage, though Arrow does not give dimensions for it split. Storage space is a concern.

The RDF one appears faster to deploy since it unfolds. I have not found dimensions for it in storage condition.

Is there a performance difference? I have not yet found a front to back rating for the Arrow. The RDF claims 10 dB.

One other thought was the loop Arrow produces.

Thanks in advance.

Go with the RDF - it's well made and works great, including as a handle.

Thanks! Any comparison on performance? Is it worth more that double the cost of the Arrow?

I've not used a loop antenna before, so I can't really say anything about that.

However, I would say go with the RDF boom as opposed to the Arrow boom. The Arrow antenna has to be broken down by unscrewing each element, which takes a lot of time. This means that most of the time in the field, it's going to be fully assembled and difficult to get in and out of vehicles and other tight spaces. The RDF antenna, on the other hand, folds up similar to the old Little L-Pers, though the main boom doesn't fold.

The Arrow and RDF are both comparable on accuracy, precision, and range. For me, being able to fold up and store the antenna was worth the extra money at the time; but if it's not worth it to you, then the Arrow is a great option.
