The all new E-04 ELT is a direct replacement for the more than 62,000 model E-01 ELT's (by ACK) on the market today. The new E-04 fits directly into the current E-01 mounting trays and uses the same remote control panel indicator. The E-04 external antenna will utilize your current antenna mounting and wiring installations.
Accepts GPS position input data from Bendix/King. Garmin, Nema 0183 GPS
New antenna is swept back 20 degrees, and features a molded plastic base.
5 watts @ 406MHz for 24 hours, and 100 Mw @ 121.5 MHz for 48 hours.
New simple plug in audible alert indicator.
New lithium battery pack offers a 5 year battery life, and makes it substantially lighter.
I installed an E-04 replacing the old E-01. It could not be more simple. A new battery into the panel switch, replace the main unit and plug in the speaker, and remove and install the new antennae, and your done. Whole thing took two hours at the most. The quality is reasonable. The price is very realistic, these guys aren't gouging you.
I installed one of these units on my plane 4 years ago. Yesterday a student accidentally pushed the transmit button on the sub panel. *while the plane was still in the metal hanger*. I got a call from the air force wanting to know if everything was OK.!!!
If you need an ELT... this is the one to get.

I installed an E04 two years ago with a full pannel upgrade. It is on its 3rd battery--they're VERY expensive, must be shipped by ground, haven't been stocked East of the Mississippi and there is no way to check its (battery's) status untill it is known dead. Also cannot check the 406MHz signal data content at the 3 Avionics shops which have changed the battery!
One of our distributors ask me to respond to the comments by the Dayton Flight Department. We have never been contacted by anyone from this company and cannot find any listing on the internet. To date we have delivered over 9300 E-04 ELT's. We have had no battery issues other than when people inspect the ELT and place the red cap over the switch without reading the manual and inadvertently turn it on without an antenna. The later model ELT's have a warning sticker by the switch.
They may be confusing us with a similar looking competitors ELT that has been having issues with battery life.

An ACK, Model E-04 saved my father, and my life on September 9th, 2012. For ultimate survival, we also recommend an additional hand-held McMurdo 406 MHZ, PLB.
Before installing be sure to have a CR2 3-volt and a Duracell PX-28L 6 volt battery on hand. It won't work without them and are not included in the kit. I would like to have a few words with the designer(s) who couldn't figure out how to make a system that doesn't need additional batteries, and requires two types of different voltages at that. The need for batteries is bad enough, but how about at least a common battery such as AA or AAA?
This was a very easy installation. The tray mounted right where I removed my old ELT and tray, and there was plenty of cable to make it to the front for the remote switch. You do need to purchase two small batterys, one for the remote switch, and one for the audio alert indicator,about $20 extra, they are good for 10yrs though before replacement. I'm quite happy with my decision to use this ELT.

Responding to Mike Akatiff's assertion there are no battery problems: The Installer might have wired the unit incorrectly to cause battery drain, but it SURELY was not on otherwise the CAP or NOAA would have notified me. Radio shop tests confirm there is power radiating from the antenna when on, and it stops when off is selected. Perhaps it is a defective unit--I shall contact ACK and discuss a warranty replacement. I have rated it 3-stars because I don't have enough data to rate it 1-star. I have just ordered my 5th replacement battery!!! Louis Leet / Dayton Flight Dept

ACK requested that I send them the ELT I mentioned before was eating batteries. I don't know why I didn't do just that a couple years earlier... Their Repair Department found a defective Circuit Board in the unit, replaced it and re-certified the unit as Airworthy (8130-3). Kudos to Mike Akatif and his team for great customer support and a rugged product. Thanks! Lou Leet
The two additional and different battery design for the buzzer/switch panel really is DUMB! Why not use the aircraft power in place of them? If necessary, optically-couple the LED/buzzer outputs for electrical isolation of the ELT from the aircraft power. The outputs ARE anciliary to the ELT's primary function.
The remote and GPS cables are not properly stress-relieved against flex-induced failures at the ELT body exit.
If ACK used standard 8-pin RJ-45 (LAN) modular plugs for the remote connection, COTS boots could be used for the strain-relief on the cable ends, and you'd have a growth path (existing conductors for backwards compatibility) for any future new functionality. You could also use SHIELDED cables, for RFI rejection, too.
I agree with the need for mechanical protection of the unit's BNC antenna connector (the ACK approach is sound), but it can be hard to get at/connect, once you've installed the ELT in the aircraft.
What is the difference between the USA and international version?
If you have a USA registered aircraft you will need a USA version (programmed for the USA). If you have an aircraft registered outside the USA you will need the international version in which we will need to know the country of registration so we can specifically program. You can fly any where in the world the key is programming to the country of aircraft registration. What is the difference between complete (new install) and retrofit kit?
If you have an ACK E-01 that you are replacing you can save some money and buy the retrofit kit as you already have parts installed that the E-04 will use. If you do not have an E-01 then you will need to buy the complete kit which will be a new installation. Does the ACK E-04 ELT transmit your GPS coordinates as well as 406?
By it self, no you will have to connect the E-04 to an external GPS to gain this feature. Refer to the manual for how to connect. How does an AP/AI test the unit at the annual condition inspection for proper function? Are there any special tools/equipment needed to test?
All of this is stated in the E-04 manual but a unit self test and checking lines for any corrosion is about all you need to do. No tools are needed and cost will only be the time to do the self test and check the lines. I'm interested in the ACK E-04 to replace a Narco 901 ELT, so I need the full installation kit. What else do I need in terms of panel indicators, etc. that are not in the package. Are there other required parts/special wire to connect to my Garmin panel GPS (530W)?
The E-04 is complete 11-06395 (For USA registered aircraft) for a new installation. For GPS connection you will need to refer to section 6 of the manual (on the Document Tab) which tells you what wire you will need based on your installation. On page 6, immediately above Figure 9, there is the statement ...to connect the ELT RS 232 data and power to the aircraft systems. Is the ELT to be connected to Aircraft Power? I thought their power was independent from the aircraft.
In most cases yes the ELT is independent of aircraft power unless the manual state so and in this case is require if you add GPS information to the ELT. Does this ELT meet the requirements for the 406 required for Bahamas travel? With a new installation kit, is it approved for installation in the PA28-180?
The Ack 406/121.5 MHz E-04 ELT will meet the future Bahamas 406 Mhz Requirement and is approved for installation in a PA28-180. What is the battery replacement item for the ACK 406 E-04 ELT?
The replacement battery for the ACK 406 E-04 is part# 11-10012. What is included for a new installation?
The ACK 406/121.5 MHZ E-04 ELT comes with the ELT, Antenna, Remote Switch, Alert Buzzer and wiring. Is a whip antenna available for the AKC-406/121?
Yes, the Whip antenna for the ACK 406/121.5 MHZ ELT is P/N 11-10465. Does the new install version of the ACK 406/121.5 E-04 ELT include a mounting tray?
The new install version of the ACK 406/121.5 E-04 ELT includes a mounting tray. Is this ELT approved for installation in a 1952 Cessna 170B?
All ELT's are TSO'd but do not have an STC for any specific aircraft so a 337 form must be filled out. Does the new install kit for the ACK 406/121.5 MHZ E-04 ELT include the cables to connect the remote control panel indicator and the audio alert?
This wire is not included. Instructions on wiring are documented in the instruction manual.
