Hi Glen,

We don't supply the BNC cables for the Multicoupler.

We are taking orders via the PayPal buttons on the web site.

Paul,

Your amplifier has most of the changes except for the change to allow operation up to 15V.

Hi Chris, I received my Loop Antenna Amp only two or three days ago, when purchased it was described as the “New Version”. Can you advise me whether the amp I purchased is the latest ‘+’ version?

Thanks Chris for the emails , and for your speedy reply.
At the moment I was wanting to order your Multicoupler and also are you able to supply the BNC link cables to the radio’s or do I have to source elsewhere. 
And am I still ok to order via the PayPal link on the website 
Regards Glen

The situation as of the 14 April is that I can still access the workshop on my own and continue making some products.

We have stopped making products that took significant workshop assembly and are now only building batches of HF/VHF/UHF Multicoupler, Loop Antenna Amplifier + and High Z Antenna Amplifiers.

We have also stopped making custom versions of our products especially since the supplies of some RF connectors have dried up. For example it's no longer possible to buy a good quality SO239 socket at present as they are all on backorder from our suppliers. There's lots of junk ones out there but we don't use them.

We are also restricting shipping runs to the Post Office to once per week so this may add a delay to dispatch depending on the timing of the order.

If anyone is desperate for a rapid delivery we can quote and arrange to send via DHL at cost.

So in answer to the original question if it's a Multicoupler, Loop Antenna Amplifier + or High Z Antenna Amplifier we can ship from stock with a weekly postal run or via DHL.

Loop Antenna Amplifier +

Chris Moulding
 

We have just brought out a revised version of the Loop Antenna Amplifier called the Loop Antenna Amplifier +.

There have been a few changes made to the base unit amplifier to improve stability with some of the non-50 ohm input SDR receivers out there.

The main changes are to the head unit to allow it to be powered from an external  bias-tee with a supply voltage up to 15V. It also has reverse polarity protection in case of a power supply connection error. It can still be powered with a 5V bias-tee source such as a SDRPlay receiver. The RF performance is unchanged throughout the voltage range.

This will allow some of our customers to connect it to their existing antenna installations using 12V bias-tee power.

We are also offering the Loop Antenna Amplifier + head unit on it's own at a reduced price for users with their own bias-tee systems.

More details on the web page:

Chris

Subject: Re: [CrossCountryWireless] Hi Z Antenna Amplifiers

 

I've been surprised at the amount of advice and help following my post on the Topband contesting email reflector. I've had several direct emails with advice too.

What I'm proposing to manufacture is a Hi-Z antenna amplifier. This is is designed to be used with a 5m vertical element (aluminium tube or wire up a fishing rod and a ground or earth rod into the ground. This antenna arrangement can be used on it's own as a low noise receive antenna or with anywhere from 2 to 9 identical antennas in a phased array to produce a steerable directional beam for DX work on 160 or 80m (or the other HF bands).

The amplifier has to have a very accurate and repeatable gain and phase relationship between input and output so that users only have to adjust the coax lengths between several antennas and a central switching unit to construct a phased array.

It also has to have the highest IP3 performance possible so that it isn't overloaded by local medium wave stations.

I've built a prototype using a recently introduced IC from Analog Devices originally intended as a high IP3 buffer stage in front of ADCs in SDR receivers or similar products. During initial testing at the workshop signal to noise tests on a local medium wave station 20 miles away are the highest of any antenna I've tested there.

The design will allow it to be used with 12V or 5V bias tees and there will be two options 75 ohm F type or 50 ohm BNC connectors.

The production PCBs are being designed over the next few days so I expect to have some ready for sale in about a month.

The amplifier will be mounted in the same polycarbonate box used for the Loop Antenna Amplifier and I'm aiming to sell it at the same price.

Regards,

Chris

 


Re: Loop Antenna Amplifier - Service Bulletin 4 - HF performance improvement

@sdoros
 

Thanks for your suggestion, signals decreased but didn't disappeare. I was watching SDR spectrum with a mobile device while I was shorthering the cable.
There are still some strong signals at some frequencies.
Even at those frequencies they are not, the noise is at very high levels around -80 or -90 dBm below 30mHZ.

A λ/4 CB antenna has a much better reception and less noise at all frequencies below 30mHZ than loop antenna amplifier.
This means I can't use the amplifier, unless you have something else to try.

A recent post in one group featured a picture of man (if I am permitted to assume that) surrounded by empty beer bottles. No one thought this was distasteful to alcoholics. No comment about said person smoking which in the face of a respiratory virus, killing people faster than smoking-induced lung cancer, should surely be even more offensive. The empty bottles were strewn about haphazardly, a nightmare to sufferers of OCD.

 

To add, my brother is an advanced paramedic, who is otherwise fit and healthy, has just gone down with a bad cough, sore throat and shortness of breath. No PPE and no testing kit/equipment. That’s offensive but beyond my ability to do anything to change that situation. Paramedics are often the first to jump to black humour. Its one of their coping mechanisms.

 

My wife has Crohn’s Disease and has had two large sections of bowel removed, the result of which is she lives with permanent diarrhoea, and has done for about fifty years. Medication I take for diabetes often builds up and puts me into a similar state. You would think then that we would we offended by all the toilet roll jokes but we see the funny side and just deal with it because be don’t let trivialities get us down.

 

So you understand a bit more about me, I suffered a massive stroke about twelve years ago which has left my mobility impaired, along with other problems not immediately apparent. Some of those problems are mental in that my short term memory is terrible, and I suffer from a form of emotion lability where I don’t often look ahead to think about the effects of what I am saying.

We could all serve ourselves better by exhibiting patience, tolerance, and understanding in the difficult times in which we find ourselves. The Scottish poet Robert Burns said it nicely in "Ode to a Louse"

O wad some Power the giftie gie us 
To see oursels as ithers see us!  

Of course, it's likely that my Brit fiends will chew me up for taking a Scottish poet out of context, but at least I'm not mangling Shakespeare (yet) :-)

Stay well!

Re: Cross Country Wireless High Z Antenna Amplifier.

Chris Moulding
 

Hi Vince,

Yes it's the high Z antenna amplifier we discussed on the Topband mailing list.

The first batch is nearly completed and the production boards test OK. As expected it works great on 160 and 80m DX but it gives excellent results on long wave, medium wave and the NDB band too.

I was planning to add a post about it once I've made a video about it tomorrow morning.

It still has the loop antenna video as a space saver at the moment but I'll update that tomorrow.

Here is the link to the web page: http://www.crosscountrywireless.net/high_z_antenna_amplifier.htm

Chris

As a super picky engineer testing it on a network analyser I would say yes there is a difference, a few dB here, a few dB there.

As a keen radio amateur or short wave listener monitoring real on-air signals with noise and fading you would probably wouldn't notice the difference.
