Howzit Mario, re quad shield RG6 … nothing wrong with it, it too has foam core insulation like my suggested Webro WF100.
Only concern is its over kill for FM, its designed to be used with Cable & Satellite TV and HDTV.
Its intended to be installed into F Type connectors, so not sure how it will accept the 75ohm Coax plug you need for your NAT-03
@Gigantor … 75 ohm coax
Naim work best with a STRONG signal. Just because there may be no audible hiss doesn’t mean you will experience the full potential of any Naim tuner.
I used a 3 element roof mounted array for a few years before installing a Ron Smith Galaxy 17, only then did my NAT 01 show what a live broadcast could sound like. There was a much wider soundstage, deeper bass and placement of instruments within the orchestra. Listening now to BBC R3 is, in my opinion, as close as one can get to a live performance.
Yes agree, but that applies to any tuner. I would say that it especially applies to Naim NAT-01 and 02’s with their made in house front ends.
The OP on this thread has a NAT-03, which together with the later NAT-05’s, all have outsourced ALPS or Philips tuner heads and have a sensitivity much like all modern tuners.
I agree your findings with the Ron Smith ’ Galaxie’ aerials. My NAT-05 used to have a a 3 element, but when I changed it to an RS G14, the soundstage and presence, especially with live broadcasts, is so much better. That said; the main TX and its BBC’s with 50kW is only 5km distant.
An added plus with the G14 is that I’m now able to pull in more previously un-listenable local & semi-local low power stations.
lol… at that distance and power you could probably hear radio three from your dental fillings 
Of course you can overload an FM discriminator front end… although FM is hugely more tolerant than AM in this regard … you can abuse the signal with FM to quite a degree… though the reduced signal quality may affect stereo.
On my communication tuners I have RF attenuators for this… but that is more for AM and SSB.
Your comment had me wondering (hypothetically) if my NAT05 with a ‘Galaxie’ would be better than a NAT01 with my Yagi, all other things being equal.
Your experience says, yes.
I would say no…
A Galaxie is a modified Yagi design… that helps with greater FtB gain and rejection, a broader bandwidth resonance, and higher gain in a smaller boom length amongst other things.
The discriminator is only one of the considerations, as well as the demodulator and analogue gain stages. Now you can read of the deficiencies in the NAT01 design as a tuner, but it can sound very appealing with its audio outputs … and that is what counts in the end.
My NAT05 I acquired second hand doesn’t sound that great to me… yes it’s clear and sharp, but not super appealing, it almost sound like online radio channels… I much prefer my NAT03… and although I haven’t done side to sides, it pales against the NAT01 allegedly.
Hmmm?… only a comparative test in your location (TX distance) can answer that.
But having spent a lot time with a NAT-01 with a 4 element dipole, my bet would be on the NAT-01.
The NAT-05 is a OK/good receiver, but nothing like a NAT-01, in my case the 05 just got that much better with the G14 in my location.
Thanks both. I just thought all those antennas on the gable end at the factory (none of which look like mine) must count for something.
Ive owned a NAT 05 XS with an external power supply and currently own a NAT01. Used both through a rather poor antenna and the NAT01 is very much better and probably my favorite source. If it sounds better with a better antenna, and i get radio 2 and 3 very clearly with zero hiss, then it must be damned good indeed
They’re a bit further away from Rowridge than thee ‘n’ me, Chris. If I walk over one street (OK, poetic licence, maybe two streets), I can see the mast……providing it’s not pi$$ing down like today!
Which leads on the the old joke from the Solent area.
“If you can see the Isle of Wight from the mainland, then it’s going to rain. If you can’t see it, then it’s already raining”
Yes G23’s all well above the roof line, all sucking in 250kW from Rowridge at only 30 miles distant.
Salisbury, marked on the maps as “Here be dragons”? 
(Got some decent fly fishing though)
This is an amazing chat. I have no idea what is being discussed or the subject, but the detailed technical know how and what appears to be global input, is why I love the forum. Brilliant
Barely got going. Be sure to check in some time in Spring 2026 
I can strongly recommend the Ron Smith Galaxy 17. In my case connected to my beloved NAT01 
@Mario … how are you getting on with your NAT-03 project?
Did you get the aerial mounted outside & did you use the RG6?
Hi Simon, I’ve just seen this. @Mario 's aerial is a Stellar Labs 30-2460 and is a four-element folded dipole Yagi with integral balun.
I wonder if anyone can advise me on this one. More than ten years ago, I purchased a pre-owned NAT02. I phoned my local Naim Audio dealer and asked them to recommend an aerial installer. The recommended installer duly came out an fitted a roof aerial. The sound is good but I am unable to receive local radio stations in stereo. Only the BBC stations light the indicator on the tuner. I live in Mayland in Essex. Am I in a weak reception area? Thanks for any advice that can be offered.
