VK2KRR
COMMERCIAL PRODUCT REVIEWS

I have used a lot of Commercial Ham Radio products here as I need a high level of reliability, and I need it to work first time with no problems and I need the products to be high performance. 
Some manufacturers recently have been noted as giving false information about certain products and there are many false rumors and other information online that is not correct. 
This page is to give all other Hams my experience, views, opinions and performance of products I use here at the VK2KRR station.

The VK2KRR station is quite a demanding site for radio products, mostly for tower mounted items in regards to reliability and strength in the windy environment here. If a product is deemed to be an excellent product for this station, you can rest assured that it will be good virtually anywhere (except maybe if you have ICE issues, which I dont).

PRODUCT OR EQUIPMENT BLACK LIST- Fairly major problems with business/products listed below. 
Be aware, I would not recommend these at all at this point in time.

INNOVANTENNAS / G0KSC Numerous problems with antennas supplied to me for 2m band. In particular mechanical construction issues, and overall antenna performance issues not matching what is claimed via their website, particularly in relation to forward gain, side lobes, real lobes and overall pattern. No instructions were supplied, as they had never even built the antennas before and I was supplied instructions from a different antenna. 
There was no offer to replace or refund money. When you pay extreme amounts for supposed 'the best' antennas, you expect them to work with no problems.
M2 ANTENNAS USA Issues with a number of yagi antennas supplied to me. 
Construction and mechanical stability poor on some antennas.
Antennas provided were not correctly tuned and elements, in particular with the 162 MHz yagis I had, I had to CUT some of the elements myself to get it close to the desired frequency. In 162 MHz case, nearly an inch off each side of driven elements!
When you contact them and explain there is a problem, they do not respond or do not attempt to resolve, replace or refund money.
When you pay extreme amounts for supposed 'the best' antennas, you expect them to work with no problems.
