Tuning it is not going to cure the problem, putting in a RF choke is just going to hide the symptoms. A dirty choke is coil of your coax made of 5 turns with 4.25" diameter for 27MHz and it needs to be at the antenna which clearly isn't really realistic in a mobile install. As mentioned you need...

No, the flat metal disc doesn't connect to the foil, well not directly. You can however check for continuity by making a very small hole in the center of the foil, putting a probe there's another metal disc there that's attached to the one you can see when you remove the top section that I guess...

I'm not sure whether to hug you or hit you for bringing this back up :LOL::LOL::LOL:. Seeing that post made me paranoid I'd not checked when I fixed mine years ago when the braid came desoldered so I just took it apart to check. Good job I did because the rubber waterproof sleeve around the...

Almost all tubular metal antennas are built from aluminium tubing. So what's the problem? The main issue is not whether the aluminium is good for a RF ground, it's about the physical strength of the bodywork to support a mount with an antenna on it.

Unfortunately it is unlikely to do what you want, at least for local comms. For local comms it's pretty much line of sight so if there's a hill or mountain between you and who you want to contact it's not happening no matter what. You'd be able to work DX, stations from long distances away...

"SWR makes you stupid." My thoughts are don't bother trying to chase 1:1 SWR. Antennas that have a wide 1:1 SWR are generally lossy. The reason you get 1:1 SWR flat across the board when using thin coax is because of the losses in the coax. As long as the SWR is no more than 1.6-1.8:1 across...

Sorry but this is just plain wrong. The only difference between changing from horizontal and sloping is all other things being equal it changes the feedpoint impedance so you need to retune the antenna. The reason it won't tune is because if you have a large metal roof you have got an...

You want shorter, not longer. Out of the factory the whip lengths are made assuming a piss poor installation, typically a magmount thrown on the roof or trunk. The more efficient your RF ground the shorter the antenna needs to be for a given frequency. The problem when you've done a really good...

The performance is fantastic. I used one on a single 10m band entry in the CQ WPX contest a few years ago and at just 16ft managed to work China from UK longpath with 100W.

Because they know CBers will believe any old bullshit when it comes to antennas and be happy to part with their money to "rectify" a non-existent issue. For example here's a ground plane kit for mobile antennas, ignoring the size of the radials do you spot the problem with it functioning as a...

400W PEP will be fine. I doubt it'll do 1500W without issues.

Loads of them over here in Europe.

The Imax 2000 is not trash and is very durable. Mine is well over a decade old, sits on top of a 20ft pole and the UK is one of the windiest countries in the UK. The only problem with it is you need to wear gloves now handling it because of the very fine fibreglass splinters. The most likely...

You're removing the board to replace it, there's no other way around it.

If you're lucky with the coax or mast length it may not. If you're not lucky they'll make a difference. The problem is that the difference that people like yourself expect....the S meter to go higher than before to those you rabbit to on Ch19, is generally not the difference you'll get.

You must be talking about the US market. Over here in Euroland....

This is a fairly recently released radio though. Its £189 from my favourite radio shop.

Just use RG58. The lengths of the cable runs are so short in a mobile installation it doesn't matter a shit, you'll not be able to tell the difference. Hell I've even used RG174 to get from a lip mount to inside the vehicle.

Nope. It's about the frequency response range of the element, the cardioide pattern of the element and the microphone. But more importantly it's about how high you have the mic gain up on the radio than the mic used. The vast majority are just way too high. On my ham gear I rarely have mic...

They'll detune each other due to capacitive coupling so you may find you need to cut a bit off the CB antenna to get the SWR down as they'll appear electrically longer. The dual band antenna may be the most affected out of the pair, you'll definitely need to check the SWR on it.
