Expensive and Worth It !  Time owned: 3 to 6 months
Best watt meter I've used in 40+years, period.

for the $ a little dissappointing  Time owned: 6 to 12 months
almost as soon as I got my 4510 the 4520 came out, I called alpha about trading up and they wanted my meter and $400...whatever. now they want $50 to to a firmware upgrade that should be standard issue from the factory. This certainly isnt the Alpha that made my 77Sx, or the one that we all grew to know, love and respect. A couple of years ago I tried to order a new 99, but due to the fact that one lady was on vacation they couldnt take any orders. I bought a Commander and am oh so glad I did.I fear that alpha is merely riding on the coat tails of what used to be. Sad.

Excellent.  Time owned: 0 to 3 months
The quality and accuracy of the Alpha 4510 is superb. It blends the best of analog and digital technologies and all the information I need is there at a glance.

The directional coupler is integrated into the control unit so it is not possible to mount the coaxial cabling away from the control head. The benefit is that unlike meters with sensor cabling, the 4510 is not susceptible to RF at high power and maintains its lab-grade accuracy across all power levels.

The analog meter is LED back-lighted with an "ice blue" coloring that is especially easy on the eyes.

I own several commercial-grade wattmeters and this one ranks among the nicest.

Another Fine Alpha Product  Time owned: 0 to 3 months
Just as I went thru many amplifiers until I bought an Alpha I also went thru many wattmeters. Most work ok but the accuracy and consistency leave much to be desired. The 4510 is the answer. No other wattmeter that I have owned even comes close to the quality level that Alpha has put into this meter. The look and feel alone spell quality not to mention how well it operates. If you can stand the price I say go for it. I know you'll be pleased.

Outstanding!  Time owned: 0 to 3 months
The Alpha 4510 wattmeter is built like a tank! Very solid construction, and a nice "heavy" feel. The unit is just beautiful to watch operate. Nice large green digital display. I especially enjoy the brightly lit analog display. The wattmeter is a "no brainer" to use, and works flawlessly. Hats off to Alpha! Thank you!

Unsurpassed Quality and Service!  Time owned: 0 to 3 months
This meter is a testament to the quality products and service that Alpha provides their customers. The meter is a finely crafted instrument that not only provides a high level of accuracy but also exhibits the pride of workmanship that is the hallmark of Alpha. Service is a top priority with this company and it extends to not only their multi kilobuck amps but also their lesser priced products. One may take issue with the cost of this meter but if you want to be absolutely certain that you are operating your expensive transceivers and amps at their peak performance and you are protecting your investment, you need go no further than selecting this meter.

The last Watt Meter you will ever need  Time owned: 0 to 3 months
The Alpha 4510 Power meter is a true Laboratory grade meter. When temperature stabalized the meter is capable of 1 to 2 precent error. The Delivered power setting is a great feature that gives the operator the power that is actually reaching the antenna. It subtracts the reflected power from the forward power to give delivered power. The unit is very rugged and well built. It even surived UPS shipping.

This meter makes the Bird meter playing for second place. It is a great compliment to the Alpha 87A.

The manual is well written and very informative.

The only negitive I can find is the use of serial connectors that must be on com port 1. I think in this day and age a USB cable should have been used since most laptops no longer have serial connections.

Alpha has made a very impressive unit that will give reliable service for a long time. IMHO it is well worth the price if you need reliable accurate measurments of power and SWR

The last wattmeter I will ever buy!  Time owned: 0 to 3 months
I first saw the 4510 at Dayton this year. I was a bit shocked upon learning the price so I asked the guy at the booth about the accuracy of the meter. He said +-5% and I wasn't impressed. For over $1000 I think the accuracy should be +-.1%, but we all know this isn't possible with a wattmeter. The sales guy didn't have much to say about my response and needless to say I didn't buy one. Instead, I bought an RF Applications VFD and saved enough money to cover next years expenses.

I wasn't happy with the bar graph display on the VFD nor was I happy with the fact that both the bar graph and digital display changed in set increments. It wasn't fluid like an old W4 analog meter and I didn't like it. In my opinion, if I am tuning my amplifier and the output changes by 10 watts, I should know it. The VFD didn't adjust smoothly to small changes in power levels.

Last month, I broke down and bought the 4510 and I have not regretted the decision once. It is the finest meter I have ever owned. It can simultaneously provide information about forward power, reflected power or SWR on the analog meter while displaying PEP or delivered power with a large digital display.

It provides all of the information I need at a glance. It is big and the displays for both analog and digital are large and easy to read. It is smart enough to shut itself off when not being used and you can't even ruin it by hooking it up backwards as the meter automatically senses the direction of RF flow!

Besides its awesome features and functionality, it looks fantastic sitting on top of my IC-7800 or Alpha 87A.

I won't waste your time discussing all of the features of this fine piece of equipment as you can read that on Alpha's web site, but I will tell you that I will never have to buy another wattmeter! If you have been a ham as long as I, you probably have spent more than $1100 on watt meters over the years. If you buy this one, it will be the last one you ever purchase!

A great product!  Time owned: 3 to 6 months
I bought S/N 0003 at Dayton this year. This is, without a doubt, the finest RF meter I've ever owned in 45 years of hamming, it beats the pants off every other power/SWR bridge I've used. Super easy to use and well thought out. I really like the standby mode - it powers down and waits for RF to hit it, then it lights up and gives you the data - so I leave it on all the time. The time constants for the digital display and analog meter average out variations but still respond fast enough for manual tuning and such. It's got a slick look and the large meter/LEDs are easy to see across the shack.

Is it worth $1100? Only if you want the best!
