Decent SO239 Magmount

[morgz84]

My bog standard Moonraker turbo magmount is suddenly giving unusable high SWR. I suspect it has become waterlogged as did it's predecessor. The only ones I can find on Ebay seem to be more of the same fayre. Can anybody recommend a decent waterproof magmount. I don't want to keep having this issue. Many thanks.

If you dont want "this issue" Morgz84 ? = Sirio 145 single magmount base,or you can go for a triple magmount base,but the 145 will still be on your car at 70 mph (easy a100+ morelike if using a Sirio mobile antenna) and will give you years of not getting water ingress,but only if you look after it properly

Many thanks, I'll take a look at the Sirio 145 mount.

Go for the Sirio 165 mag-mount if you're into green-laning or rallying The extra 20mm may help matters.

What antenna are you going to use Morgz84 ?

Sorry I'm late replying. I have got a Modulator antenna.

Yep, bigger the magnet, the better then

Sirio Mag PL-145 and a 3/8 adaptor.

Hi Simon. This is Chris near Abingdon. Long time no copy. I think I will definitely try the Sirio 145. These Thunderpole / Moonraker turbo things seem to be garbage.

Hello there Chris, yes i don't really get on air much now. I have given up on the hom3ebase installation so only really get on air occasionally as a static mobile.

The Sirio Mag Pl-145 is really good, if it will hold a 4000HP I am sure it will hold a modulator.

Moonraker stuff was always garbage and the newer stuff is no exception.

The Sirios are £29 incl. P&P. Perhaps see if anyone's got a second-hand one, or maybe an aerial for sale on ebay that's got one on.

There's an alternative for £15 posted here but I don't know what the strength of the magnet's like compared to the Sirio's:

I can roughly compare the strength of a large "Turbo" magnet and a Sirio 145 as I have both. Just let me know and I'll sort them out and give them a quick pull/tilt test.

I'm actually tempted to buy the whole Sirio 145 antenna. It seems so have good write ups and is similar to the K40 I once had, but at a sensible price. I don't get too good an SWR with the Modulator, and tend to run it through a tuner. I only ended up with the Modulator as it was randomly given to me by a neighbour who used to be into CB back in the day. I started using the Modulator after my K40 fell to bits and I didn't have the cash to replace it at the time. Not to say it it's a bad antenna, I've had many good copies on it, although I tend to put up a Firestik when I am static mobile.

I've got the CB-Line mil145 branded version of the Sirio mil145 aerial, on a Sirio 145 mag. It seems pretty good for the size. I would like a 6ft Sirio, but no one in the UK stocks the particular one I want.

The Modulators do tend to need larger magnets as they're longer, with a longer coil and a long, floppy non-tapered heavy whip if it's an original one. It means that the centre of gravity is a lot higher, therefore requiring more magnetic force to keep it planted firmly, especially if green-laning, driving down country lanes fast, or a bit of council estate rallying

I lost both my base-loaded and twin-loaded Modulators off my Mk1 Escort, the base-loaded one swung off the roof and down the side of it, making a lovely arc-shaped scratch in the paintwork which had to be T-cut out!

I had the taller, twin-loaded one on the boot with a 7" mag' but still managed to knock that over too, so I changed to a Tagra t40 (almost identical to a K40, but with a much better locking system). Driving like a loon doesn't help matters when you're 17

I wanted to fit the t40 to my Espace IV a couple of years ago, but discovered the boot hatch is mostly fibreglass, so it wouldn't clamp on well and would have been a pain to earth it to the metalwork.

I have never had any issues with my Modulator, I SWRed it on one car when I first got it and it has been swapped between several vehicles with no adjustment needed.

Something like a Sirio HP4000 should easily outperform a K40
